I'm using a TabControl and have overridden the DrawItem event to produce my own background and foreground colors for the header text. It looks good but there's still grey color around each header. I thought maybe the Padding property could be set to (0,0) but that seemed to have no effect.
View 2 RepliesATM I'm trying to color individual items on my combobox. While reading stuff I googled, it seems that the only way to do this is through the DrawItem event.My question is, will the draw item be 'called' when i assign text to the combo box? combobox.text = "string"
View 18 Repliessub I use on all forms in my app I would like to put in one central place (of course right). in vb.net I put this sub in a module it has a "Handles tabcontrol1.Drawitem" - I get an error saying handle requires with events variable defined in containing type or one of its base types.also when I refer to tabcontrol1 in a module it wants to know which form.. Can I use sender to define current calling form?
sub
Private Sub TabControl1_DrawItem(ByVal sender As Object, ByVal e As System.Windows.Forms.DrawItemEventArgs) Handles TabControl1.DrawItem
Dim g As Graphics = e.Graphics
Dim tp As TabPage = sender.TabControl1.TabPages(e.Index)

I have a program and wish to generalise its appearance at startup on different machines. This worked OK until I moved it onto a Windows 7 unit with a 22" screen. The front page covers less than 2/3 of the screen. I know I've asked the system for 'working area' but could not find a reference to the entire screen which other applications seem able to use. How can I catch up with them? The code is from VB in VS2005. Is this my limitation?

In my VB application I have a tabcontrol, with 3 pages, the first page is for some contact data, the second page wil show the website of your contact and the third page shows the location of you contact (I used the webcontrol). when I switch from page 1 to page 2 or wathever, the text in my textboxes disapears en my first page. It happens most of the times, sometimes it just works but most of the time it freaks out.

key = dataset4Category(i).DataSetName
name = Space(1) & StrConv(dataset4Category(i).Tables(0).TableName, VbStrConv.ProperCase) & Space(4)

View 3 RepliesI have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is).

View 3 RepliesI am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?
View 1 RepliesI want to raise an event for an opto-input state change but not sure if I can. Basically I have 4 opto-inputs on a PCI control card - one of which changes pretty rapidly - that I currently poll with a timer. I'm looking at getting a proper hardware counter for that but the other 3 are production status indicators. I'd prefer it if they alerted the app to a state change though.
Depending on the state of one of the inputs I have to fire a relay which simulates a button push. Having been playing with serial ports and getting a very useful app built for logging production data into a SQL Server DB I want to re-visit a proof-of-concept system I built a few months ago.
Current code - which works fine - but I'd like to change is like this:
Private Sub tmrOptoInput_0_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrOptoInput_0.Tick
'Read OptoInput_1 to Monitor Track State...
Dim aType As Byte ' replace Byte with any other type
[code].....
Having 4 inputs so I need 4 timers, plus another one that polls the database and checks a status flag which triggers the app to start logging. I'd like it to be event driven rather than timer driven if at all possible but I don't know how and there's nothing in the control card docs. Also I can't seem to find anything relevant on the web.
Is it possible to assign the MouseDown event handler or equivalent to an image (from ImageList) of a tabcontrol without using OwnerDraw? I can add images to tabs through ImageList. And I can draw something that looks like a close button on each tab, using OwnerDraw. But I notice that the tab sizes will be fixed regardless of the tab labels. I want the tab sizes to be flexible with the labels. For now, the second best alternative to assign events to tabs seems to be use of contextual menus. But it's true that some people just don't want to right-button-click on tabs.And I have seen a project where somebody uses a 32-bit library declare. And I can't use it because I only develop 64-bit apps.

I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

A little background... I'm trying to build a spell checking form. I have this lovely library: [URL] and it seems to be working flawlessly.
The problem I have is trying to replace an entire word and only the first occurence of the word.
Example: Replace the first instance of "foo" with "bar" in the following string
"foo foo foobar" and get this "bar foo foobar"
I've been trying regular expressions with no luck. Here are the patterns I've tried compiling(these are obviously tied to variables in my program):
"(?<!foo)foo"
"(foo){1}"
I also tried the built in string.replace method with a count parameter, but I have no idea how I would make that match the entire word.
