Refer To A Windows Form Control By Name (C# / VB)?
Jul 24, 2009
Suppose I have a label control on a windows form called "UserName". How can I refer to that label programmatically using the label name? For example I can do:
For each ctrl as Control in TabPage.Controls
If ctrl.Name = "UserName" Then
' Do something
End If
Next
This seems quite inefficient. I would like to do something like: TabPage.Controls("UserName").Text = "Something" I did some googling but couldn't find a satisfactory answer. Most suggested looping, some said .NET 2005 doesn't support direct refenece using string name, and FindControl method was asp.net only...

In VBA from Access 2003 I was able to employ the following :Form.Controls(" in here I am able to use a string variable holding the name of the control I want to reference ").property= etc.Is this kind of thing possible in VB .netI have a listview control to which I am adding 'errors' and the tag property of each item hold a string that is the name of the control I want to set the focus to when they double click on the listview item. So I want to do something like this :<listviewitem.tag>.focus()and have the string interpreted as a control name.

Im working on a project and just wanted to know to make a control refer to itself?I know that by using the word "Me", the system refers to the form but how about the control. I know that i can simply name the control (e.g. txtSurname.Clear) but if i was to use the code on multiple controls it would save alot of time if the control could simply refer to itself!

I'm an Access/VBA programmer new to vb.net. In Access I can do this using the controls collection of form, but I can't figure out how or even if I can do it with vb.net.
I want to change this:
'tcpWeek(x) is a tab control page
My.Forms.frmBookMain.tcpWeek1.Text = "Mytext1"
My.Forms.frmBookMain.tcpWeek2.Text = "Mytext2"

How do I refer to a form in my project by using a string variable? I'm running Visual Studio 2008.My main screen has a number of dropdown menus that, when an item is selected, a form will open:
Dim Mdi_frm_Doors As New frm_Doors Mdi_frm_Doors.MdiParent =Mdi_frm_Doors.Show()In this example, I am providing the name of the form directly (frm_Doors). What I would like to do is refer to the form as a string variable.I'm already doing something similar to access specific controls on other open forms (where str_Field is the name of the control I am accessing):

I'm trying to create a windows user control project that has a textbox placed on it.I want the textbox to fill the user control window.I've built the control and added it to another project, but it isn't behaving the way I want it too.When I drag and drop the control from the toolbox onto a windows form and try to resize it, because the textbox.multiline property has been set to True, the Textbox resizes horizontaly and not vertically (just like normal textboxes do) however the underlying user control window resizes which is undisireable. How can I get the user control window to stop doing this.

I have a VB windows application and I need a way to control input output from this windows application to a batch file.The batch script is quite complex so converting to a VB console application is out of the question because it will too much time.An simplified example is this:I have this batch file test.bat(just for example)
@echo off
set /p choice=name : %choice%
echo Hello %choice%!
In this batch file the user input the name which is then stored in a variable and after the user press enter on the screen will appear Hello + user input.
1. Is it possible to enter the name in a textbox from the windows form and by pushing a send button pass the name to the batch application and then the batch file to continue the operation of displaying the Hello message?
2. After the batch file finishes the operations it will open another console windows (3) with status of the various operations that take place on the system(in my case connected users to a server)Is it possible to hide this child console windows that are generated after my main .bat application finished the operations of opening connections?Can this be done from the windows application or I need to modify the .bat script?
3. Is there a way to collect the console windows output in a textbox from the windows application?One idea that came to me was to redirect the console output to a textfile and then read the textfile in the VB application but I want to know if there is another way.
4. Is it possible to hide this batch file inside the windows application exe?

I have a spreadsheet control on a windows form that I would like to populate with data from an existing worksheet (myworkbook.xls, sheet1). The best solution for me would to be to actually open the workbook on my form (not sure that is possible?), the next best solution would be to fill the spreadsheet control.

I have a customer which as a Visual Basic Project in single instance mode with a wired presentation logic.
The main form contains a TabControl with mutliple TabPages.If I click on TabPageA another form is shown in front of the Form and resized to have the same size as the TabPage.
If I click on TabPageB the first form is hidden and another form is displayed.So basically for the user it looks like you have a TabControl with different TabPages which is not the case.
I tried converting the Forms to UserControls and put them inside the TabPage, but, thanks to the SingleInstance app, this would take a whole lot of refactoring. I tried it but eventually gave up because of many many runtime errors and I don't want to put any more effort in this.

I am writing a Windows form application where a client has the ability to add as many chart as needed in the form by clicking at an icon in the menu bar at run time. These charts will have the same format, and I will have them linked to a text box for the client to select which entity to chart.I have no clue where to start. I did a web search and I have found articles that show how to add user's control at design time (I don't think it is what I want).
