I have populated a label in VB.Net using what has been input in a text box on another form however, when i then try and use the content of that label in a piece of code, it shows that there is nothing in the label?

How would you change the Form size depending on the width/length of a Label?
I need to resize a Form depending on how much text there is in a Label (the text is automatically generated from case statements).
You can try to put the AutoSize to True of the Form
Open the Form and put a Label on it , the Label gets a Name lets say Label1.
Rightclick on the Form and open Properties
Then Choose AutoSize to True
Then return to the Form and dubbleclick on the Form this case Form1, Form1.vb is open.
In Form1_Loadif it is another Label you have to adjust it to the right Name:
Label1.Text = "This is a example text and a bit longer zo the form is getting bigger"
Run it and there it is :

I have an Access Table named Count. It has one field named Anz and it has only 1 record. I want to Show this record in a TextBox on a form named overview. So in the design mode of the form inside the TextBox I use the code
[Count]![Anz]
but it Returns me #Name? error when I Switch back to form mode. Where am I going wrong?
You can use in Control Source of your unbound text box =Dlookup("[Anz]","[Count]")
Also you can bound your form to Count table and use for text box control source Anz
I don't quite understand the differences between the combobox properties SelText and Text.
If I want to send the content of a combobox as a parameter to another procedure, should I send .text or .selText?
If I want to make enter text into a combobox using a macro, should I write the text in .selText or .Text?
The difference is really given in the name (SelText vs. Text) where Sel stands for Selected. One is used to return or modify the selected text (i.e. SelText) and the other is used to return or modify the entire text (i.e. Text).
If no text is selected in the ComboBox then they return and modify the same value.
I suspect you want to use Text unless you are specifically interested in the selected text.
This appears to be consistent for an ActiveX control on a Worksheet or for a control on a User Form.
I am a student programmer who is learning VB. I am trying to make a telephone book type project in VB (Windows Forms). In my project I am using an unbound Data Grid View control. Below the Data Grid View, I have some textboxes which will display the values of the selected row. On the form load event, my program accesses a file and populates the Data Grid View control with values from the file. This works perfectly, but the problem I get is when I use the code:
txtLast.Text = dgvMain.Rows.Item(0).Cells(0).Value
to populate the textbox called txtLast with the value at the specified cell, the textbox doesn't display the value. The program doesn't crash or hang, it simply won't display the value and when I try to edit the textbox, it acts as if the textbox is empty. I have tried using
txtLast.Text = dgvMain.Rows.Item(0).Cells(0).Value.ToString()
as well as trying to refresh my Data Grid View control and the textbox. Nothing has worked so far. When I use a breakpoint to see whether that line of code is executed, the autos window shows me that the line of code is executed and that it sees the value of the specified cell as "Smith". However, when I press F11 to step into the next line, the textbox.text property remains as "" instead of changing to "Smith".
Note: when I manually specify the text through the code (i.e. txtLast.Text = "Test") it will show that text. Also, this problem is not with just one textbox, it is with every textbox that I use (I have 5 textboxes showing various values from the specified row). The weird thing is that out of the 5 textboxes, one of them, the masked textbox which shows the phone number works perfectly with the same line of code. (note it is not a problem only affecting regular textboxes as I have tried using both regular textboxes and masked textboxes, both produce the same problem except for the phone textbox).
Also, I would prefer to keep the Data grid view unbound (not connected to a database) and the textboxes unbound (not connected to the data grid view as a data source) because while browsing the internet I have seen people suggesting to bind the textbox or data grid view, however I do not understand how to do so, and I believe that this can be done without binding to a data source.
Any help is appreciated in trying to figure out why the text doesn't change. Let me know if you need any other info or if part of my explanation is unclear.
Thanks!
is it possible in design mode to set the textbox text property to the text property of a textbox in a different form in vb.net?
You could use the ApplicationSettings.PropertyBinding property of the text box to accomplish what you want. If you sort the text box properties A-Z, it should be the first one in the list in parenthesis. Just create a shared application value and it will apply to each control that binds to the value.
