.net - MDI Child Form Does Not Activate When Clicked In Client Area?
Jul 29, 2010
My VB.NET app supports several kinds of MDI child forms. Some kinds, but not others, are 'troublesome' -- they cause the focus mechanism to become weird. Once a 'troublesome' child form has been opened, NONE of the MDI child forms will become activated unless I click on either the title bar or the border. Clicking in the client area does not activate the child form -- its title bar remains gray, and it does not receive Activate or GotFocus events. Strangely, however, the clicked-on form actually DOES receive the focus, because its controls receive mouse and key events. Only the Z-Order and the highlighting do not change.
Once this problem develops, it persists even after the 'troublesome' form is closed, and it affects child forms which are opened afterward. However, if ALL of the child forms are closed, the problem clears up, and new child forms behave normally -- until the next 'troublesome' form appears.
I have no idea why one kind of child form is troublesome, and others are not.

I guess thats what I need to do, Im trying to allow the user to right click on the top of my form, and my custom Context Menu Strip is displayed, not windows context menu strip. I guess somehow i would need to get the size and draw a rectangle on the non client area and see if the user has right clicked in that rectangle? if so how would I get the area of the non client area?

I have a picture box on a form that changes size as needed. Both by resizing the form and by code.How can I resize the form automatically if I resize the picturebox in code. The client area of the picture box should not be clipped.Right now the picture box is set to dock fill, but if the code resizes it, the form does not follow it. Is there a binding somewhere I can use?

I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

I'm just getting around to it, but after many days of research I haven't come up with much, now I may not have thought of every possible search sure, but that aside I was wondering if anyone had any resources I could turn to for learning

I am working on a library of controls that clone Office 2010's Ribbon interface and theme. One of the controls will inherit the form control and will modify the ribbon to implement Aero Glass. This is what I have so far... In order to get the same look and feel, I've extended the aero glass margins exactly far enough to get this effect for the top 50 or so pixels. The ControlBox property is set to false, so that there's not an extra 30 pixels at the top that I don't do anything with, but now I need to get the

What is the correct way to find the client area of the webbrowser control, WITHOUT the scroll bars ?
Any area/rectangle I get from the control seems to give me the entire control size, including scroll bars wether they are there or not.
I have tried detecting whether scroll bars are present and finding how wide they are to subtract from the entire control width, but have found no reliable way to acheive this.
I am trying to find the actual size of the window I can see if when the web browser control is showing the web page, not including the scroll bars.

I have a MenuStrip with File > New, Open, Save, Exit located in a parent form, and a RichTextBox located in a child form.The problem I'm running into is concerned with the destination of the file elected from "Open" and the save.When a user selects their file from "Open", I need it to open the child form and put the text into the RichTextBox.I also need the program to be able to "Save" from a child form, whether it's been brought up via "New" or "Open".

On my program I am trying to make a form that would activate the program.I have the activation codes but when the user enters the activation code in a text box, is it possible that it would erase that activation code or wont accept that activation code again after being used once. Then if the program accepts the activation code can it open the main form (form1) and if the user closes the program and the re-opens the program, is it possible that the activation form doesn't open again and instead, going to the main form. I have this password code:
Private Sub textbox4_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MaskedTextBox1.KeyDown
Static WrongCount As Integer = 0[code].....
Then can there be slashes every 4 characters in the text box?

I'm trying to make my application become the active window if it currently isn't as soon as the mouse enters the main form of the application (so there is no need to click the title bar of form itself to make the window the currently active one if it's not).
It only sorta/kinda work .... I have to enter the form with the mouse 3-4-5-6-maybe 7 times ... then the window finally becomes the active one.
I know the MouseEnter event is firing each time the mouse enters the app, but the main window isn't becoming active most of the time.
Private Sub frmMain_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.MouseEnter
rtbStatus.AppendText("Just got a frmMain.MouseEnter event" & vbCrLf)

I have a program where the main form is called (shown/activated) via a keystroke combination. When the form pops-up, I've set the focus to a textbox to begin typing right away.
When the keystroke event occurs, I have:Me.Activate()And in the Form_Activated event:
Textbox1.Focus() Simple right? It works the way I want it to, even after I've compiled and run the EXE, but ONLY if Visual Studio 2008 is running. Once I close my project in VS, with the program still running outside VS, the form is shown, but input focus is not set to the textbox.
Input focus is however still set to whatever it was previously, like a word document for example. My form will be topmost, but if I attempt to input text, it would still be entered into the word doc. why having my projects' source open in VS has anything to do with running the compiled EXE of said program?
I've even tried API calls to SetForegroundWindow and ShowWindow with the same result.
