I have a DLL file containing a few different classes. Inside this DLL i've created a Windows Form.
After building the DLL project, I opened up PowerShell (I used ISE for convenience..) and executed the below script -
[reflection.assembly]::LoadFile("...\MyDLL.dll")
$NewForm = New-Object (AssemblyName).(Class Name of a class with a few subs, one of which will show the form I created)
$NewForm.ShowForm()
ShowForm is a simple sub that shows the windows form by calling the forms name and .Show().
When I execute this, and the form appears, the form hangs. It's almost as if the entire form is disabled. I can't interact with any controls on the form, nor can I close it by pressing the red X at the top.
I'd like to store a few forms that go with methods I've created in DLL files, so that if I decide to use a form to go with them in other applications, I won't have to rebuild the form.
(To anyone who's wondering why, then, I'm using powershell - I feel it's easier to test out functions / subs in a DLL from Powershell first, since 3 lines in a commandline tool like Powershell can easily call a sub / function from a DLL instead of creating / modding / recompiling a .exe project to do the same)
Any time I ever try to use a form object in PowerShell calling the .Show() method, it always seems to fail. You might consider trying .ShowDialog(), which blocks the current thread from doing anything until it exits, but the session doesn't hang. I haven't researched the "why" behind this yet, but for what you've described, I'm assuming .ShowDialog will work for you.

I've been trying a solution for this, but. I cannot find it.
What I'm trying to do, is work with the "bind by reference" ability, but working with ILE RPG written with embedded sql.
I can use the BNDDIR ctl opt in my source. And everything works correctly.
But that means a "bind by copy" method. Checked deleting the SRVPGM and even the BINDDIR. And the caller program still works.
So, is there any way to use "bind by reference" in an ILERPGSQL program?
After my question, an example:
Program SNILOG is a module, that conains several procedures. Part of them, exported.
In QSRVSRC I set the exported procedures, with a source with the same name: SNILOG. Something like this:
STRPGMEXP PGMLVL(*CURRENT)
/************************************************** ******************/
/* *MODULE SNILOG INIGREDI 04/10/21 15:25:30 */
/************************************************** ******************/
EXPORT SYMBOL("GETDIAG_TOSTRING")
EXPORT SYMBOL("GETDIAGNOSTICS")
EXPORT SYMBOL("GRABAR_LOG")
EXPORT SYMBOL("SNILOG")
ENDPGMEXP
As part of the procedures are programmed with embedded sql, the compilation must be done with CRTSQLRPGI, using the parameter OBJTYPE(*SRVPGM).
So, I finally get a SRVPGM called SNILOG, with those 4 procedures exported.
Once I've got the SRVPGM, I add it to a BNDDIR called SNI_BNDDIR.
Ok, let's go to the caller program: SNI600V.
Defined with
dftactgrp(*no)
, of course!.
And compiled with CRTSQLRPGI and parameter OBJTYPE(*PGM).
Here, if I use the control spec
bnddir('SNI_BNDDIR')
, it works fine.
But not fine enough, as this is a "bind by copy" method (I can delete the SRVPGM or the BNDDIR, and it is still working fine).
When I'm not working with SQL, I can use the CRTPGM command, and I can set the BNDSRVPGM parameter, to set the SRVPGM the program is going to be called. Well, just their procedures...
But I cannot find any similar option in CRTSQLRPGI command.
Nor in opt codes in ctl-opt sentence (We have BNDDIR, but not BNDSRVPGM option).
Any idea?
I'm running V7R3M0 with TR level: 6
Thanks in advance!
the use of
bnddir('SNI_BNDDIR')
Is the way to bind by reference OR bind by copy.
The key is what does your BNDDIR look like?
If you want to bind by reference, then it should include *SRVPGM objects.
If you want to bind by copy, then it should include *MODULE objects.
Generally, you want a *BNDDIR for every *SRVPGM that includes the modules (and maybe a utility *SRVPGM or two) needed for building a specific *SRVPGM.
Then one or more *BNDDIR that includes just *SRVPGM objects that are used to build the programs that use those *SRVPGMs.
I'm having this problem for a while now and google have its limits.
I'm writing a powershell file that contain several generic function.
I use the function in vary scripts and now I want to let other personal in my work to use them as well.
the problem is, do to sensitive operation, I want to lock and protect the script (compile to a dll, exe etc').
how do I create powershell library like C# DLL?
one option I try but did not find out how to continue is to compile the script using powerGUI to executable file ( .exe) but then I canot access the function in it let alone pass on parameters to that function.
hope you understood me :)
thank you.
You don't. Rather than trying to obscure this information (if you compile them, they can be decompiled and your "protected" resources will no longer be), remove them entirely and make those parameters for your functions. This both protects your "sensitive" data and makes the code much more reusable.
You can then package your functions into a module
So I am working on some IIS management scripts for a specific IIS Site setup exclusive to a product to complete tasks such as:
- Create Site
- Create App Pool
- Create Virtual directories
The problem, is I would like to keep separate scripts for each concern and reference them in a parent script. The parent script could be ran to do a full deployment/setup. Or you could run the individual scripts for a specific task. The problem is that they are interactive, so they will request for the user information relevant to completing the task.
I am not sure how to approach the problem where each script will have a script body that will acquire information from the user, yet if it is loaded into the parent script avoid that specific's scripts script body from prompting the user.
NOTE: I know I could put them into modules, and fire off the individual "Exported to the environment" functions, but this script is going to be moved around to the environment that needs setup, and having to manually put modules (psm1) files into the proper PowerShell module folders just to run the scripts is a route I am not particularly fond of.
I am new to scripting with Powershell, any thoughts or recommendations?
Possible Answer*
This might be (a) solution: but I found I could Import-Modules from the working directory and from there have access to those exported functions.
I am interested in any other suggestions as well.
They way I would address it would be to implement a param block at the top of each sub script that would collect the information it needs to run. If a sub script is run individually the param block would prompt the user for the data needed to run that individual script. This also allows the parent script to pass the data needed to run the subscripts as the parent script calls the sub script. The data needed can be hard coded in the parent script or prompted for or some mixture thereof. That way you can make the sub scripts run either silently or with user interaction. You get the user interaction for free from Powershell's parameter handling mechanism. In the subscripts add a parameter attribute to indicate that Powershell will request those particular parameter values from the user if they are not already provided by the calling script.
At the top of your sub scripts, use a parameter block to collected needed data.
param
(
[parameter(Mandatory=$true, HelpMessage="This is required, please enter a value.")]
[string] $SomeParameter
)
You can have a deploy.ps1 script which dot sources the individual scripts and then calls the necessary functions within them:
. $scriptDir\create-site.ps1
. $scriptDir\create-apppool.ps1
. $scriptDir\create-virtualdirectories.ps1
Prompt-Values
Create-Site -site test
Create-AppPool -pool test
Create-VirtualDirectories -vd test
In the individual functions, you can see if the values needed are passed in from the caller ( deploy.ps1 or the command line)
For example, create-site.ps1 will be like:
function Create-Site($site){
if(-not $site){
Prompt-Values
}
}
The ideal is to make the module take care of maintaining storing it's own settings, depending on distribution concerns of that module, and to make commands to help work with the settings.
I.e.
Write a Set-SiteInfo -Name -Pool -VirtualDirectory and have that store values in the registry or in the local directory of the module ($psScriptRoot), then have other commands in the module use this.
If the module is being put in a location where there's no file write access for low-rights users (i.e. a web site directory, or $psHome), then it's a notch better to store the values in the registry.
Hope this Helps
Just installed rails 3.1 rc1 and am trying to grok the best way to manage javascript with the new asset pipeline
By default all coffeescript is compiled into a single application.js file, this is a good thing.
Each seperate coffee script file is appended to the js file and wrapped in an anonymous function which is executed via the call method
A common scenario would be to use some jquery to turn various forms into ajax forms, update UI, etc...
Many of these scripts will be specific to a controller or action, I am trying to grok the 'conventional' way to handle this,
since everything is wrapped in an anonymous function how do I only execute just
the code for a particular controller / action, by default all of the anonymous functions are being executed
I did play around with some hacks where I load the controller and action name into js variables and then in
coffeescript check those to conditionally run code, I don't like that very much
my initial thought was that each coffee file would contain a js namespace/object and I would call the specific ones from the view,
going to spike this using the default_bare = true configuration
see How can I use option "--bare" in Rails 3.1 for CoffeeScript?
EDIT
Looking around some more: this looks like it might be the correct approach - "Can't find variable" error with Rails 3.1 and Coffeescript
There are two common approaches:
Make behavior conditional on the presence of a particular element. For instance, code to run a signup sheet should be prefaced with something like
if $('#signup').length > 0
Make behavior conditional on a class on the body element. You can set the body class using ERB. This is often desirable for stylesheets as well. The code would be something like
if $('body').hasClass 'user'
gistyle is a simple gem that helps you running action-specific javascript codes.
By following its setup, you set some data attributes in your body element, representing the current controller and action names. Then it will only call that action when the corresponding view is loaded.
In the past I've been able to embed a sripting languate (like JScript) inside the SQLCLR, so scripts can be passed as parameters of functions, to perform certain calculations. Here is a simplistic example (the function ssScriptExecute returns a concatenation of all the print's in the script):
select dbo.ssScriptExecute( 'print("Calculation: "+(1+2/3) );' )
-- Calculation: 1.6666666666666665
I'd love to be able to embed a Powershell runtime in the same way. But I've had all sort of problems because the runtime tries to find assemblies by path, and there are no paths inside the SQlCLR. I'm happy to provide more information on the errors I get, but I was wondering if anybody has tried this!
Thanks!
I use il code injection to modified System.Automation.Management.
make variable version in GetPSVersionTable() be "2.0"
then i can run Powershell Code in SQL Server.
Be sure reference this modified dll in your visual studio project.
http://www.box.net/shared/57122v6erv9ss3aopq7p
btw, automated registering all dll you needed with running powershell in SQL
you can use this ps1 code
http://www.box.net/shared/tdlpu1875clsu8azxq4b
I think the only way to do this is to create a WCF service hosting powershell, and let SQLCLR send the request dbo.ssScriptExecute(...) to that service for execution.
Besides from that, I've also successfully embedded paxScript.net in the SQLCLR (an interpreter that does not have the memory leak problems of the DLR languages).
I thought SQLCLR was restricted to just a certain set of assemblies and PS Automation is not one of them.
