I have a program built with VBA, in access.
I have a form with the field chDate and I need to get the value of the field in a module file named Global (not class module).
I tried to access it but I think I get empty value, string. not error.
I'm no expert with VBA, its new to me (I have experience with VBS).
Can someone please help me and tell me how can I access the value of a form field via module file?
Thanks!
If you can provide some sample code, it might help us in trying to get you a solution.
Here's what might work:
Dim an object as an instance of your form, and set the instance to a new instance. These two lines will do that (assuming the form is called frmForm)
Dim theForm as frmForm
Set theForm = new frmForm
then Show that Form:
theForm.show
The form will get the focus, so you can populate the fields. At that point, once the form is hidden, your code should be able to pull the field as such:
var1 = theForm.txtFormField.Text
However, if you unload the form in code, all variables directly tied to the form will be lost. In that case, you might want to follow Oneide's example, and set a global variable to the value of the form field. You can do this in one of the form's event handlers.
Let me see if I can recall my Access days. In your global module you should access the form field be prefixing the form name i.e.
var1 = Form1.txtFirmField.Text
As far as I know, you're trying to get the data the wrong way.
Anytime you would try to get your form data, from a standard module, your form probably will already be closed or, if you're not opening it as a restricted window, the value will not be ready yet.
Anyway, if you could get pass through all the difficulties above, you're probably coding in a not standard / right way.
Remember that VBA is an event driven language, and you would be better using it's strenghts rather than fighting against them.
As a final word, if this is just a casual coding, I suggest you using a global variable and make de Code Behind Form have set it up on control's change event.
If you're not sure what I mean, please leave a comment and I'll try to explain it better.
And, if you don't mind, let us know more about your starting code to get better answers.

I have a simple form that's in a dialog fragment used to submitting two fields for log-in auth.
For simplicity I was hoping to not have to use data binding, but rather use some method to gather all data inside my sap.ui.layout.form.SimpleForm.
I added a name property to each input element which says in the docs it is " Defines the name of the control for the purposes of form submission."
https://openui5.hana.ondemand.com/#/api/sap.m.InputBase/controlProperties#name
However hard as I try to find there doesn't seem to be any getFormData methods.
All SO questions and guides either use data binding to a model, or hard-code references to the individual input controls with .getValue() methods.
And looking further into the form API, there doesn't seem to be a Submit event either.
Given an arbitrary form, what would be the best way to gather all submission values without hard-coded references or data-binding?
Would a method that walks though all the children elements of a form looking for all submission values work? I think it might, but there are more submission input types then just the input component.
You can get the value of the fields by directly using;
var oField = sap.ui.getCore().byId('IdOfTheFieldAtTheDialog');
var sValue = oField.getValue();
But it's always better and convenient to use data binding which keep things neat.
And If I assume that you have the id of parent form container, you can iterate over the items and get the sap.m.Input elements in it without knowing the IDs of the individual inputs, and you may check the name property of the fields if you want. Check this snippet;

When I submit my form I am getting an error from my cfinsert function because there is not a database column name "SEARCHFIELD". The problem is "SEARCHFIELD" is not an input in the form I am submitting.
Both forms have close and open tags so I am not sure why my search form input is being referenced in my main forms submission?
Any thoughts?
Two ways I can think of to avoid this, without seeing your actual code it is hard to guess where SEARCHFIELD is coming from. As some of the comments pointed out it would most likely be from a CFPARAM or the name of your submit button in the form.
The first way you could tackle this is the CFINSERT tag has an attribute named formfields where you can list off the columns you wish to insert with. You can see that here in this doc link:
http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7c78.html
Another way you could do this is you could add code to remove SEARCHFIELD from the FORM scope prior to running the CFINSERT. Which would be as simple as:
<cfset StructDelete(FORM, "SEARCHFIELD") />
You could check to see if it exists and if so then delete it but the StructDelete() will run without issues even if the field does not exist.
I personally do not use CFINSERT/CFUPDATE and I know the default opinion in the community is not to. They do have some benefits though that often are overlooked in that they do parameterise the SQL and offer at least some safety from malicious people. Without knowing anything about what you are doing it is hard to say if using them is actually a shot in your foot in the long run or something just fine to be doing.
I am new to VBA and am currently still studying the most basic ideas of the language. I haven't gotten that far in my VBA Code studies to write the code I need by hand, so, in the mean time, I have been using the VBA Editor to enter Property Values via the Properties Window. This has been proving far more difficult than I anticipated. My Goal is to create a drop down list for a VBA Form. I understand one of my options is to reference a range of cells in my excel worksheet by inputting it into the value field located right of the ControlSource Property. My attempts to input the desired range always comes up with the same error:
Could not set the ControlSource Property. Invalid Property Value.
I have tried looking in the VBA Help files and even searched online. I haven't had any luck finding the proper syntax to enter into this field.
I am assuming I may run into similar issues as I try to set other property values through the Property Window. Thus, I am diligently studying my VBA courses so I can simply write the raw code. But that takes time and I need this form to work as soon as possible.
Is there anyone out there that wouldn't mind lending me their brain for a moment? I would be most grateful. Having this working would bring a lot of stress off of me.
Thanks for reading!
What tigeravatar mentioned, works fine for me, for the ComboBox as well for the ListBox.
If I enter =a1:b5 into the ComboBox' RowSource, I see the values of the cells if I open the form and the Combobox. Tigeravatar's notation with $ and sheet! may be more reliable for the productive version.
The RowSource is where the boxes get their displayed items from. The ControlSource is where the chosen value finally is linked to. So if I write just A10 to the ControlSource, then open the form, then pick a value, close the form, I see the chosen value filled to the Excelsheet field A10.
Sometimes it helps to start a fresh UserForm and to add some simple fresh controls. If you seek around, you will probably alter property values that influence the behaviour in an unexpected way, and then you get lost. I have tested with Office 2010. If you have another version, it may be important to forum readers to know.
I'm creating a multilingual Drupal site and trying to implement a search function, that only displays results in the current language, that the user is viewing the site through.
Using Drupals own searchfunction at /search/node it is possible to select which language to search for through the "Advanced search" options, and it works perfectly. However, I dont want to expose these language selectboxes, I just want it to only search in the current language automatically.
What's the best option to do this?
I have one solution where I create a hook_form_alter function, that sets the #default_value in the language selectboxes to the current language, and then I hide the whole "advanced options" with in css. This doesnt seem very right though.
I think the most clean solution would be to hook into Drupals form-processing process and append ex "language:en" to the input text, but I cannot get this to work.
Does anyone know if it is possible via one of the Drupal form related alter functions, to get a hold of the input text and alter it before drupal does its final processing of it?
To answer your question specifically, while using 'hook_form_alter', you have a referenced variable called '$form_state'. This stores the values in the form, and any change there will be passed further.
Also,
I think setting a default value and hiding the field is a good solution as any, only, if you are hiding it you should do it server side, while altering the form. The same field you are setting the default value to. like this:
$fieldname['#type'] = 'hidden'.
I'm creating my form using the Form helper, so the action of the form is specified automatically....
this form is used for editing a post..
so, the URL has the structure: mywebsite.com/posts/edit/id
and the form's action should be automatically generated as posts/edit/id
but the problem is, in some cases, I open the HTML code and I find that the form's action is only posts/edit without the id which causes the update to fail...
I spent a lot of time to figure out what situation brings this wrong action:
i'm generating fields dynamically (using javascript & ajax) depending on the post's category..
when the value of one of the dynamically generated fields is invalid, the generated action becomes posts/edit !!
I really need help, cuz I don't know why this is happening !!!
and I don't wanna waste more time digging into the core of cakephp...
so, if any of cakephp experts has an idea about this, plz help me !!
thank you in advance !
Use the url parameter, which allows you to explicitly define a url for the form:
echo $form->create('Post', array('url' => $html->url(array('action'=>'edit', $id))));
It sounds like $id probably isn't getting set, because it should be getting passed along if it is. You need to make sure it's set to edit the record in question. Make sure your javascript is including the hidden field with the record's id in it.
Normally done like this, with the form helper: echo $this->Form->input('id');
Also, if one of the fields is invalid, the form shouldn't actually be submitting properly, if you are using cake's validation, so this is to be expected.
