I know that with the Command Button, you can utilize the PerformClick option. I would like to know how you would go about doing something similar for a Combobox.What I am looking to do is open the Combobox within the GotFocus method.
View 2 RepliesThe problem is that the method is getting called multiple times when the text box control gains focus. I am looking for it to just run once since the method is filling the text box control with data. Is there a common reason this happens? Its not looping cause it is happening on everyone of my controls that use the GotFocus method.
View 7 RepliesI have two web browser controls on my form. I also have several buttons like bold, underline, etc. My probem is the gotfocus of the web control is not working correctly. If I click on the web browser control to add text the gotfocus is not fired. If I click on a text box first and then click in the browser control it is fired. I need to know which has focused so the bold etc know which control to work on.
View 1 RepliesI have been searching for a while and not able to find anything useful on how to approach this issue.I have a ComboBox on a form and what I am looking to do is when the ComboBox has the cursor focus, it automatically opens up and displays the options. Just as if you clicked on the ComboBox. I was considering PerformClick but the only problem is, I believe PerformClick is only available for the Button and no other control.
View 2 RepliesI am trying to use the open file dialog box in VB 2005 to open up an existing txt, or rtf file from a directory into a rich text box.

I use to be a VB6 developer before migrating to .NET.
I am looking for a way to do something (as in, call a procedure) whenever a textbox gets focus in ASP.NET but I couldn't find my way out. I am using VB.NET.
I working on a project that includes to call a certain type of method to each control, i have this
Private Sub txtBcNum1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBcNum1.KeyPress
[Code]...
This code works like a charm if i want to allow only numbers and backspace on my textbox.Problem: I have 15 textboxes( txtBcNum1,txtBcNum2,....,txtBcNum15 ), what's the best way to call this function inside KeyPress method on each textboxes with out manually adding it to KeyPress method?
I am looking for a way to tell when a tab has taken focus. I tried the gotfocus call but it doesn't seem to get called when I click on the tab. Did a quick search on google but can't seem to find the answer.

I have a mdi and 3 child windows.The program start with an empty mdi.With a menu you can open each child window once.When i open for example 2 windows. And close the one on top. The one left(the window under the one i closed) should get focus. How can i manage this?
why i need this?each childwindow has a event gotFocus. Depending on the focus my menu should change.
Private Sub frmMain_gotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.GotFocus
I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
I just added a gotfocus and lostfocus handler for all of my textboxes. Below is my routines to call on gotfocus/lostfocus.
[Code]...
Now, my issue is that this works great if you use the mouse and click around in the textboxes. However, if you hit the TAB key to move around on the screen, the LostFocus event doesn't seem to work. All of my textboxes backcolor remains lightblue. What did I do wrong? What do I need to do to fix this problem?
In vb.net I would like to set all numericUpDown (NUD) controls to select their value when they receive focus, like a text box does. Do I need to write a GotFocus handler for each NUD? I know I can use widthBox.Select(0, widthBox.ToString().Length) to do the selection I just need to be able to apply this to all NUD GotFocus events.

View 1 RepliesI'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).
So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.
I have a combobox which dropdown style = dropdown. I applied autocomplete function to this combobox. User can type and then use tab key to move next control or select from list.
Question: Which method to use in order get a name value from combobox? SelectionChangeCommitted or SelectedValueChanged?
Im struggling on how to open an excel workbook without one of two problems.
1. After the first workbook is opened and I close the workbook, if another is opened the worksheet area is "transparent", as in, you can see the desktop or any open app behind excel.
2. Closing excel and opening another workbook after X times (4+?) via the vb.net app I use causes the computer to reboot.
I am stuck thinking it is the method used to open excel within the app.The code below has two methods, both produce the same affect. One method is blocked (makes it easy to test either one).[code]I have two buttons that open workbooks, both have identical code less the workbook requirements.Is there a better or best method to use for opening excel workbooks from vb.net?
