I need to know how to set the focus to a specific tab on a multi-tab tab control.[code]each followed by a .Refresh, but the tab control stays on the same tab. Do I have to cycle thru the index to get back to the base tab on the form, or what?
View 1 RepliesI have a form with 3 controls that have TabIndex values set:Combo box (cboPostpone) - TabIndex = 0 Postpone Button - TabIndex = 1 Install Now button - TabIndex = 2
The code below is part of the Timer1.Tick event The code below seems to change the focus but then when trying to tab through the controls, it stays on the combo box.
[Code]...
Lastly, I removed cboPostpone.Focus() command from the Timer1.Tick event and move it to the Postpone button Click event. I run the focus command right after the me.hide command. I delayed it the first time and it came back with the Postpone button in focus again instead of the combo box.
I am having problem setting focus on specific cell in my Datagridview1 . On Form1 when clicking on cell 3 in any row, I am callig a Dialog1. However, when done working with it, and closing the Dialog1, the focus returns to cell 3 in my Datagridview1 . I like to set the focus on the next cell(4) making it the current cell.
I have tryed :
DataGridView1.SelectionMode = DataGridViewSelectionMode.CellSelect
DataGridView1.CurrentCell = DataGridView1.Item(4, e.RowIndex)
DataGridView1.CurrentCell = DataGridView1.CurrentRow.Cells(4)
And few other things, I am always getting this exception: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.
Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

View 8 RepliesI have read this many times. Focus is a low-level method intended primarily for custom control authors. Instead, application programmers should use the Select method or the ActiveControl property for child controls, or the Activate method for forms. What exactly is the difference?

View 3 Repliesi have a window form which has text boxs, buttons and radio buttons.when the form is loaded i want to put the cursor focus to TextboxA. But what i got is it didn't go to textboxA although I call TextboxA.Focus() at Form_Load event.In my Form_Load event() i have:
1) assign a value to a global variable.
2) hide a panel
3) set this TextBoxA.focus.
What i found is if i didn't checked the radio control to True in Form design time, the focus is go to that place, textbox.If i set the radio checked = True in form design time, focus is go to this radio button although i set TextBoxA.focus in form load line end.In my radio_checkedchanged() event, I have:
1) clear all textbox and set the focus to textbox. ( i even tried remove the set textbox focus line in this radio event but it didn't work)

I am trying to figure out how VB can focus a specific program and then send commands to the program only. The focus would only be for the commands and would not make the program you are currently in lose focus. Simply, what it is controlling is a Windows Application called GOM Player. I use it to study my material for school. I plays movies in it and don�t have to click out of the application I am working in to pause, play or rewind. The keypad and the company who make it actually have it built into iTunes and it does exactly what I want GOM Player to do.
The reason I dont just use iTunes is because I can�t get my video files to play in iTunes. After pulling teeth with the manufacture I finally to tell me that the iTunes functionality is accessible via plugins built into iTunes. So trying to mimic what is being done there does not help. I believe that a knowledgeable VB programmer could answer my question in seconds, but having some experience with coding and programing I know it also could be a lot more than what I think. [URL]
The question is: What is way that VB can send the key for the macro only to the GOM Player Application even if it is not focused or even If it is minimized.

I am setting my Winforms Button control properties to appear as a hyperlink would on a web page. I've formatted everything fine, except the border in the FlatAppearance object. I have code to act as pseudo-CSS (FormBackColor is a string constant.):
b.FlatStyle = FlatStyle.Flat
b.BackColor = ColorTranslator.FromHtml(FormBackColor)
b.ForeColor = Color.Blue
[code]....
The code removes the border from the flat Button control except on MouseOver, where I add a 1 pixel border. On MouseLeave, I remove the border. This is to show some visual feedback. This works fine when the button does not have the focus. However, if I click on the button, giving the button focus, mousing out and over again now shows a greater than 1 pixel border around the button. I'm imagining it's combining my button's explicit 1 pixel border with the traditional "Winform Button has the focus, so add a border" border around the Button.How can I disable/remove the "Winform Button has the focus, so add a border" border? Or, should I just do a check in ButtonMouseOver to check if the control has the focus, being a condition of adding the border, and just be done with it?

I'm creating some software to keep my students on task. I've set it up so that I can control certain aspects of their computer from my computer. Problem is, I'm not sure how to control other applications from my application. I mostly just want to prevent it from being minimized. Some students like to switch screens quickly when I walk by.

I am doing something similar to the calulator in windows. My form has a key_up event that allows the user to type numbers. There is also number buttons they can click. Once a number button is clicked, it gains focus and the key_up no longer works.
I looked at windows caluclator and when you click a button there it does not gain focus and the keyboard keys continue to work. How can I get this behaviour?
I am currently translating a windows form application, written in VB6, to a webpage written in Visual Studio 2010. In VB6 it is easy to find out which control has focus on the form using '.getFocus()'. I have come to the conclusion it is not that easy, if at all possible, in vb2008.
