I have it on top using Me.TopMost That part is working great but I want to leave the current app have focus, not my keyboard. I'm guessing I need to use Windows API functions to accomplish this, however, I have not found any good examples in VB.NET.
View 2 RepliesOn my Form_Load event, I simply have a code which is simply Text1.Focus and Text1.SelectAll. Neither of these actually works. I've also tried this on the Visible_Changed event and checked if the form is visible.
I can create a button with this code in and it works fine. Is this something to do with the text box not actually being visible at the time when the code is executed? It's driving me mad!

I really want to make use of the toolstrip and databinding but these two technologies keep conflicting with each other. I think the root cause is something to with the fact that the toolstrip buttons don't recieve focus in the normal way.
I invite you to try the following:-
1. Create a form and put some text boxes a tool strip with a save button on it.
2. Write a query or sproc to get a datatable back and bind your text boxes to the field in the datatable.
3. In the code behind your Save ToolStripButton put some code that makes an arbitrary change to a field on the dataset (it doesn't matter whther this field is bound to a text box or not). eg:-
m_DataTable.Rows(0).Item("CommissionRatePerc") = "0.0000"
4. Put a breakpoint in the save and run the form.
5. Make some changes in the text boxes. Do not leave the last text box but rather click save while a text box whose contents you have edited still has focus.
6. When your code hits the breakpoint, query the value of the data table field that is bound to the text box you were editing when you clicked save - it will still contain the unedited value. Unless you do something about it that unedited value is going to get saved back to your DB.
We did get around this problem by explicetely setting the focus to another control on the form before saving. That worked most of the time because it prompts the text box to flush it's value back to the datatable (nb EndEdit does not work, although you'd have expected it to). However, and this is the reason I suggested you add a line of code that changed a value in the underlying datatable in step 3, if you change a value in code in this way before the value from the text box get's flushed back then it doesn't seem to matter what you do, the user's current edit is simply lost. They will still show in the text box, though, leading your user to believe that the change has been committed when it hasn't. Our final solution is that we never ever change a value in the adtaset in the code behind our toolstrip buttons. That's working but it's a pretty big restriction.
I created a windows form which contains a datagridview. I named one of the columns in the grid 'location' which appears to have generated an error. The problem is I cannot load the form to remove the column as an error is generated and when I load the designer code it says do not modify with the code editor but use the windows form designer.

I have 7 Windows forms.The order of the forms is defined within a configuration file.I want to place buttons on each form that will show the next available options.The Next button will move the next form in the list.The Back button will move to the previous form in the list. The Finish button will execute the final piece of code.The Cancel button will exit the application.If the user is on the first form, then there is no Back button.If the user is on the last form, then there is no Next button, but there is a Finish button.
Example 1:
Form1 - Next, Cancel
Form3 - Next, Back, Cancel[code]....
I have a tab control and am adding and removing tabs in runtime. I would like to two things. 1) Remove the tab that has focus. 2) Not allow a tab to open if another instance of the tab is already added.
View 9 RepliesI've a multiform project, and one of the forms within it is a loginform created using one of the templates built in with Visual Studio. This form, when opened has no code in any of the open events, yet still manages to:
- put the cursor in the password field ready for text entry
- highlight the "OK" button
- press the "OK" button if the enter key is pressed.
How can I replicate this behaviour on other forms? I've copied the properties of the button to OK buttons on other forms but can never get them to behave in the same way.
I 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.
I have a problem removing the Focus from FpSpread to any other control in the same Form.The real problem happens when opening another form while the old form is still opened, the focus remains at FpSpread in the old form.

Does anyone know if you can remove focus from all controls on a form so a user doesn't inadvertently cause action on a control when it's unintended such as hitting Enter at the same time your app appears causing some action to occur? Do you have to leave focus on at least one control?
View 12 RepliesI 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 have 1 messagebox which has 2 buttons (MessageBoxButtons.YesNo) usually we can change the focus of the button(yes and No) with tab key and we also can trigger the button with enter key.. but sometimes, i can't change the focus with tab key and can't trigger the button with enter key.i think the messagebox lost its focus..i have to click the form, so the messagebox will regain its focus how to set focus for messagebox?
