I have a project that contains two forms, Form1.h and Form2.h.
The .cpp files of each is test.cpp and Form2.cpp.
I want to open the second form from the first through a button click, of which I already have the code for, placed inside the button1_Click method:
Form2 ^ form = gcnew Form2;
form->Show();
I have furthermore placed the include file in Form1.h (#include "Form2.h"), however I keep getting the following errors:
error C2065: 'Form2' : undeclared identifier
error C2065: 'form' : undeclared identifier
error C2061: syntax error : identifier 'Form2'
error C2065: 'form' : undeclared identifier
error C2227: left of '->Show' must point to class/struct/union/generic type
1> type is ''unknown-type''
1> Generating Code...
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I have been searching a solution for a couple of days... none of which worked.
Any help would be appreciated.
Have you included Form1.h in test.cpp?

I use the Ext "cal", when I add an Image to an Event, i got this Error:
PHP Catchable Fatal Error: Object of class
TYPO3\CMS\Core\Resource\FileReference could not be converted to string
in typo3/sysext/core/Classes/Resource/ResourceFactory.php line 430 .
When I disable the Image everything is fine. Any Solutions for that?
TYPO3-Version: 6.2.27
Show your code or the error didn't happen. ;-)
Educated guess: you use a file reference in your view helper instead of using treatIdAsReference = "1"
I've started a little game in CoffeScript using canvas.
My problem is this error:
coffee -c -o lib/ src/
/src/interface.coffee:8:48: error: unexpected end of input
#ctx.clearRect 0, 0, #size[0], #size[1]
^
I've rewrote it many times but it still don't want to compile.
Here is the code:
class Interface:
constructor : (id) ->
#canvas = document.getElementById "#{id}"
#ctx = #canvas.getContext "2d"
#size = [#canvas.width, #canvas.height]
clear : () ->
#ctx.clearRect 0, 0, #size[0], #size[1]
Oh, and can someone tell me what exactly this error means?
Thank you in advance.
Its the colon after Interface. An easy way to debug that error for future reference:
Step 1: paste problem code into the 'Try CoffeeScript' part of the coffeescript website to repro the error.
Step 2: erase or comment-out lines until the error goes away and the code compiles
Step 3: the last line you erased was the error.
Step 4: find the error(s) in that line and fix.
Step 5: repeat as necessary.
This is how I figured out what the problem was. This process also works well for the 'Unmatched Outdent' error.
I have the application which was written in Zend Framework. When I try to open the index file it give me an error:
PHP Notice: Undefined index: HTTP_X_URL_BEFORE_REWRITE in
C:\Inetpub\wwwroot\test\library\Zend\Controller\Request\Http.php on
line 326 PHP Notice: Undefined index: HTTP_X_URL_BEFORE_REWRITE in
C:\Inetpub\wwwroot\test\library\Zend\Controller\Request\Http.php on
line 326
it`s depends of this line in index.php
echo $ctrl->dispatch();
because when I coment it, application give me white site.
$ctrl is:
$ctrl = Zend_Controller_Front::getInstance();
$ctrl->setBaseUrl('/test');
$ctrl->throwExceptions(true);
$ctrl->registerPlugin(new DPCPluginAuth($auth, $acl));
$ctrl->setControllerDirectory($config->controllers->toArray());
echo $ctrl->dispatch();
and the function of liblary Zend is localized on Zend/Controller/Request/Http.php and name public function setRequestUri
Please help me ... I don't know what's incorrect in that code and what means that message.
My mod_rewrite module is ISAPI_Rewrite3_Lite
I have defined some rules in DRL file, and its my first program of creating a drl file. I am getting the error "unable to analyse expression".Here is my code:
package rules
import com.sample.Applicant.appli;
rule "Is of valid age"
when
$a : appli ( age < 18 ) // appli is my class name
// age is a variable in that class
then
$a.setValid( false ); // setValid is a method of appli
end
and getting the error:
Unable to Analyse Expression age < 18:
[Error: unable to resolve method using strict-mode: com.sample.Applicant$appli.age()]
[Near : {... age < 18 ....}]
^
[Line: 16, Column: 4] : [Rule name='Is of valid age']
Make sure in the class appli, age is either public or has a public getAge() method.
Even I was getting similar error 'Unable to Analyse Expression....' while validating a DRL file in Drools Workbench 6.4.0 Final. I checked Data Object, its fields, access specifier of the setters and getters. All seemed OK. Then I saved my data object and came back to DRL file and did validating. Suddenly the above error was gone and I saw message 'Successfully Validated'. My mistake was though I had created the Data Object in Drools Workbench, I had forgotten to save it by clicking 'Save' button.
So I would suggest you, if you are 100% sure that your Data Object and DRL files are correct, save these first and then validate DRL file again.
I was trying to incorporate file upload to my project but whenever I access the a function in the controller it gives me these warnings:
Warning (2): call_user_func_array(): First argument is expected to be a valid callback, 'UploadComponent::initialize' was given [CORE/Cake/Utility/ObjectCollection.php, line 110]
Warning (2): call_user_func_array() [http://php.net/function.call-user-func-array]: First argument is expected to be a valid callback, 'UploadComponent::beforeRender' was given [CORE/Cake/Utility/ObjectCollection.php, line 110]

The upload component that I added works fine for my cake 1.3 version.
please help
Solved it, by modifying the Component.
In cake php 2.0 all components must extend Component; failing to do this will trigger an exception.
For example:
class UploadComponent extends Component {
}
