Forms - RichTextBox User Control On Main Form - Error: StackOverflowExecption Was Unhandled
Apr 7, 2011
What I have is a user control that has two RichTextBoxes. In the user control, there is RichTextBox1's TextChanged event, I want it to set RichTextBox2's Text to the same as RichTextBox1's Text, I'm currently using: RichTextBox2.Text = RichTextBox1.Text. The user control is on the main form, when I run the application and type I get this error: StackOverflowExecption was unhandled. [Code]

I am looking for a way to be able to use the tab control on my main form and transfer all 3 other forms onto that main form that has the tab control. Problem being is that some functions are named the same in each of the septate forms i want to bring into just one for the tab control.Is there a way to separate the code for each form ON the main form of the tab control so i don't have to rename/recode each of the 3 forms i want to place on the main form of the tab control? [code]so when i put both form1 and form2 code on the main form where the tab control is, its going to tell me that i have a duplicate function name.

I have a windows application with a main form, on which a user control is added dynamically when a device connects trough USB.
On a user control, there is a thread wich is getting data from the device trough USB and when it is finished, I want to change a progressbar that is located on the main windows form where user control reside.
This is the code that is I call on the user control thread to change the progress bar value:
Frm_Main.UpdateProgressBar(CInt((AllBytesReceived / MaxBytesInFlash) * 100))
and this is a code that is called on the main form:
Private Delegate Sub UpdateProgressBarDelegate(ByVal value As Integer)

I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?

My question is, in Form 2, how can i set a value to TxtBox1 of the user control?

I've got a Panel on a main Form containing a PictureBox control on Top of a TableLayout control. Both the child controls have their docking properties set to Top. The Picture control has sizemode set to Zoom.
What I'm finding is that the picture doesn't size properly when I start the app. There is a border at the top and bottom in the PictureBox control. It's only when I resize the overall form that it's correct.
So at the moment I've got this ugly bit of startup code, just to fix the problem Me.WindowState = FormWindowState.Normal Me.WindowState = FormWindowState.Maximized
What am I missing?

When I open my child form,
frm_Analogs.ShowDialog()
It opens up the new form, but now I can not interact with my main form. It will not accept focus or allow me to interact with it.
Do I need to change the form type?

I always get this error during the Paint event: System.AccessViolationException was unhandled. The weird thing is that it doesn't happen the first time it goes through.
Here's the code.
Friend CustomFont As Font = GetCustomFont()
Private Function GetCustomFont() As Drawing.Font
Try
Dim PFC As Drawing.Text.PrivateFontCollection

I have to write an application that consists of mainly one main form, but several different things I wanna display. Pretty standard I guess. So there is a menu, some controls, and the main stuff below (ranging form graphs, tables, dropdown boxes, print preview, etc). I would like to use it like one would use frames in html, design an object that is limited to a box or panel that I define. The literature I have does not give me a clear idea of how to do this (yet). The most obvious seem to be the use of MDI, open a predefined form with no borders, maximize it before showing and remove all minimize/maximize options. But that does not work so well. The form inside the MDI parent does not fit the size that is given for it when it is loaded. e.g.
[CODE]:......................
So my main question is: Is MDI the way to go here at all or are there better/easyer ways to achieve this? If MDI is the way to go, how do I sucessfully restrict a child form inside another object, without giving the user any opportunity to resize (i noticed that I have minnimize/maximize/close buttons, even if I disable them on the child forms themselves)

I've created a windows form application in vb 2010. I've got all my forms complete and now want to add a Login screen. One the login screen, after the username/password is entered and OK is pressed, I try to open the a connection string. Obviously if the connection fails, the user has entered the incorrect credentials. If the credentials are ok, True is returned and I then open up the Main form that shows the correct items for the logged in user.

i'am having trouble in making a spell checker for vb.net richtextbox control.I have made a form with richtextbox control and a panel control. I have put a listbox control in the panel control and filled with certain words. What iam able to do is whenever i select a word and click a button the panel appears just below the word (using get position from char) and display the choice. What iam not able to do is:
1) Select each word one-by-one whenever i click a button say F1 - I know keypress event but how do i select the words through keypress. I know they are separated by spaces but iam not familiar as to how to take advantage of it. The major problem being that there can be 2-3 words together sometimes colored as red. Eg: What i want is when i press F1 first time "this" is selected, next time "is" is selected and next time "nice car color" is selected. The two things are spaces and red color but i don't get anything from it.
2) Display the panel correctly within the main form's border. Right now when i select the last word of the sentence some part of panel disappears as it hides behind the main form. Eg - only 1/4th appears and rest hides. I can't find a way to limit it from moving when it has reached the main form size. I want to constrain it between top-bottom and left-right border of main form.
