Example:
I have a main form: frmMain
and other secundary forms: frm1 and frm2
Main form has 2 buttons
BUTTON1: Open form1
[Code].....
Ok. 2 instances of frm1 are opened.
But now if the user clicks BUTTON1 will create a new instance. But I dont want this. How I can show (focus) the frm1 with tag "pepe".
Only I want create new instances if tag is different. If tag is the same, the form will be focused.
Q1: How can i make it so that my window that i want to show as a drop down does not appear to take the focus off the main form that is calling it?
Q2: The form that is dropping down has the FormBorderStyle Property set to None - thus the window does not have a drop down shadow - how can I make the popup window have a shadow?
I need to dynamically show/hide a form without loosing focus from the original form. How to do this?.

to be so simple turns out to have me scratching my head.I have a program that monitors input inside of Quickbooks. When a customer is entered into a sales order my program checks my database for any special information and if it exists, opens a TopMost window to the lower third of the screen with the information showing that is special to that customer. The problem I have is that when the customer is found and the window opens, focus is taken away from Quickbooks and given to my newly opened form. Is there a way to prevent this so that the users input isn't interrupted?
With frmMessage
.Width = Screen.PrimaryScreen.WorkingArea.Width
.TopMost = True

I've created a small form that acts like the office notifications (fades inout above the notification icon tray)I'm having problems showing this form, I want to display it without the focus being taken from my main application (or any other form), I've managed to get the attached code doing roughly this, (using Me.Activate to take back focus) But this isn't great - focus switches for an instant plus I want to show the form from various areas in my application...
Dim frm2 As New frmNotification()
frm2.TopMost = True
frm2.Show()
Me.Activate()
If my form does not have focus and I click on a menu item (think File, Edit, View) the sub-menu does not appear. All it does it return focus to the form. I have to first click to give the form focus and then click on the menu. Most other programs do not behave this way. Is there anything that can be done to change it.
View 2 RepliesI would like to show a Form without focus - PLUS - I would like to have 'Enable Application Framework' enabled on the My Project > Application form. Having 'Enable Application Framework' enabled allows trapping of unhandled exceptions project-wide.

What I am trying to accomplish is this: I want to be able to press the F5 key on my keyboard, while playing a PC game, to show (bring forward, focus, etc.) my program. My 3 attempts so far have failed. Any idea on how I could accomplish my goal? Similar posts on other forums say to set the form's key preview to true and use on keyPress... which failed.
View 1 RepliesI have a simple login field, which works fine with the exception of one quirk. The form is set up with the tab order to go to the UserID first and the Password text box second. This works fine when the form is used the first time, but when the form is used the second time the focus in placed in the Password field. If the form is used a third time, focus is moved the OK button, that is each time moves to the next tab order. I even tried to set the focus in the Load event as in Me.txtUserID.Focus(), but this doesn't change the behavior. Again, I should note that I close the form and not hide the form.
View 3 RepliesI 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".

Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.
View 1 RepliesI have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
recommend a book that focuses on the .NET framework in general and isn't too language specific.
View 3 RepliesI 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 6 RepliesI want to show a message box to as the user if he/she wants to save changes. The problem is that the message box shows up behind my current form, and the current form does not have focus and is disabled. I have to switch a another program/window then when I switch back to my application, it finally shows the message box. Same thing happens when I compile and run it compiled. I also tried "MsgBox" with the same problem.
This is the code i'm using:

Private Sub frmMain_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

I am doing this on a Windows XP (SP3)
I'll try and describe this correctly. a simple datarepeater (databound, winform) with a button on it, clicking the button on the datarepeater opens another form with an uploading routine, you select the file from your hardrive, and you can send the file to it's destination on a server. the problem is when the button is clicked, the previous datarepeater template or instance still has the focus and the file gets uploaded to the wrong place, how can i, when the button is clicked, give focus to the datarepeater template that the button is on. if i click on the template, and then click the button, then the proper focus is true.

View 5 RepliesI am working on a timing program and have a start button programmed to clear all the variables and start timing events. I have another button programed to stop the timing and show the data. The problem is that when I place the cursor on the start button and press the left mouse button it workes fine, but when I move the cursor to the stop button and press the left mouse button the start buttons 3D showes that it was pressed? Since the start button clears all of the data there is nothing to display in the text boxes. If I press the left mouse button again the stop buttons 3D shows that it was pressed. Have looked everywhere for a hint as to what to do but have found nothing yet.
View 12 RepliesI have an app that calls another executable and then minimizes it until I need it. But when I do this, my app loses focus and when the user types into my app it inputs unwanted input to the minimized external application.

I want to know how when you focus on a textbox in your form, how you get the cursor to go to the first character, instead of the middle/last/etc.
View 4 Repliesform1 (startup) has buttons which show form2 and form3. when I press the button to show from2, form3 or form4 and set focus to a txtbox in form2, it does that, but after 2 to 5 seconds focus jumps back to form1 without my doing anything. This happens only on starting the program - if I click on form2 where I want to be, everything does OK from then on, but I don't want the user to have to do that. There is no timer on any of the forms. forms 1, 2, and 3 stay visible at the same time per design, but the focus always reverts to form1. I have tried many combinations of showing form2 and form3 (and form4), but with no change. I have also changed properties of the forms which I think may have something to do with the problem - no luck.I can't find anything in the help file which addresses "form focus changing". [code]
