View 1 RepliesI was wondering if there was a solution to replacing the tab control's tabs with custom tabs made in Photoshop. I know there are plenty of super expensive programs that can do it, but I was wondering if there was a way to do it programmatically. I was thinking that maybe it could linked in some way with a .DLL?
View 1 RepliesI am about dead certain that in VB Express 2008 that I was able to have multiple tabs. And, on each tab I put controls. I could also click on a tab and see the controls only on that tab.I am now in Visual Studio Pro and I cannot for the life of me look at what is on a specific tab. Only the first tab wants to shows its controls.Does anyone know how to enable the environment to allow me to view the controls on different tabs?!

View 1 RepliesI have a setup/configuration utility that I am making. The form is split the left side has a nodeview that allows the user to select what they want to setup/configure, and the right side displays that screen.
I figured the easiest way to switch between those screens is to place them in a TabControl, but I dont want the tabs to display when its compiled. How can I turn off the display of the tabs?
is there a way to remove all the tabs on a page so that i can just bring back the one i want? this is for VB 2008 by the way.

View 3 Repliesi am creating an activeX control... in this control i want to manage what the tab key does. i may a user interface that allows tabs in the textbox or it might move the user to the next screen. i have everything working in the IDE, but when my activeX is loaded into the 3rd party application the tabs no longer trigger the key down event. i assume this is because the parent application has tab stops is there a way on a control by control basis to stop the normal execution of tabs?

View 14 RepliesI use VB. NET 2008. I'm starting to work with the Tab Control and command will want to know about techniques such as adding tabs at runtime using this control.
To illustrate what I'm saying, just take one checked on your browser or in the VB (Start Page, when we add other forms to our project).
I have a application with a tabcontrol. I dynamically open new tabs on which there is a custom control which is made of a graph and a datagridview with data. I fill this from a csv file. when I open few tabs like this my application memory goes over 120 MB. When I remove the tab I call the dispose on the custom control and a dispose for the tab. But the memory stays where it was (120+MB). It goes down only if I minimize the program. And when I show it again its around 10MB.
View 3 RepliesUsing vb.net 2008 Forms. I have a groupbox consisting of several textbox's and a push button. I put this groupbox in a control collection in order to validate each texbox when the push button is clicked.
The code to do this is as follows:
Private Sub bn_updateadditem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bn_updateadditem.Click
Dim InvalidInput As Boolean = False
Controls.AddRange(New System.Windows.Forms.Control() {Me.GroupBox1})
Dim ctrl As Control
For Each ctrl In Controls
[Code] .....
This worked great. However when I moved this groupbox with all its controls onto a tab, the groupbox contents disappeared from the form after the control collection is created and contents validated (per above code).
I noticed that when using a single letter as the title on a tab of a Tab Control , the tab is bigger that it should . Look on this example :
The above Tab Control behaves normally because the text on each tab is sufficient to keep it big enough . The lower Tab Control , however , has its tabs too big . Is it possible to reduce its width ? I saw there is an ItemSize property of the Tab Controls , but unfortunately I can only modify the height of the tabs . No matter what value I set for its width , the width remains always the same (and larger than it should) ...
I'm having some problems when using this controls together, i have a small application that i made for a friend that intends to maintain data from people (clients). I used the tab control to separate the type of info, and use a global button to call the TableAdapterManager Update All command (i have 2 more tables in the database that have names of citys and types of professions to make it easy to fill all the data), some times it works others no... "Error Update 0 of 1" The form was built with drag and drop operations...

View 5 RepliesMy code is basically a file parser/editor and it handles most files fine as they hold a handful of records concerning family members. However there are a few files that crash when trying to deal with them. Here is the problem.Each family member record creates 3 tabs that hold an average of 3 group boxes each. Each group box holds an average of 3 text boxes.So each member record creates 3x3x3 = 27 text boxes and some files get up to 289 family members which = 7803 text boxes.
The problem is the rare file with 400+ member records = 10,800 text boxes which causes a crash due to using up all the window handles. Each member has a separate tab page (with 3 subpages) but really only a dozen or so member pages are visible in the GUI with scroll arrows to move through them so I was thinking of somehow making the GUI a scrollable window so the tabs get built, displayed and disposed as the user scrolls left and right through the member tabs.
The files are parsed into a 3d list DataList(x,y,z) where x is the page number, y is the group box number and z is the text box number. So all the data is available. The code then traverses MyList and builds GuiList(x,y) where x is the page number and y is the groupbox number with all the textbox.text linked to MyList(x,y,z) locations so all text changes are reflected in the MyList.
I already have a memberCount variable and I am thinking of building, say, the first 30 member tabs with the middle 10 being visible in the GUI. If the selected tab > 20, then dispose of the first 10 tabs and create tabs 30-40.I am thinking I will keep all the member tab pages so I don't have to deal with inserts and indexing problems but just dispose all the group boxes and text boxes for tab pages out of view. I already have a deep clone sub that clones members when the user wants to add a new family member and I am thinking I will have to add something similar when a tabpage is passed in for disposal, it traverses and disposes each text box, then disposes the group box for each group box on the tab page.Additionally, another routine will rebuild the group boxes from the data held in MyList(x,y,z) when a tabpage(x) is passed in.
remove the tabs from the TabControl and just buttons to control which screen is shown.Ive coded a form that uses buttons to hide and show panels but because you cant click buttons in design view, its extremely hard to edit the content in the panels.

View 11 RepliesI moved this from the debugger thread as I got no responses.This may be a better area.I have a problem enabling a Scrollbar on a custom control I have created.The custom control has one component,the scrollbar and an area that I draw upon from an internal datasource.Think something like a textbox.In certain instances,I want the scrollbar to be enabled. The Custom Control's job is to do this when the situtation is appropriate.I have a very simple piece of code here:
If <logic conditions> Then
DataScroll_vscrollbar.Enabled = False
Else[code].....
This code is in my OnPaint routine (along with a bunch of other drawing related stuff).Essentially I've determined that there is more stuff to display than the area of the control and need to turn on the scrollbar to give the user of the control the ability to see later stuff.With the exception of this funny behavior, the control is doing exactly what I want.I step through this and have a watch set.I can step through the set to True, but the Enabled value doesn't change.Even the EnabledChanged event fires (Doesn't on the set to False because it's already False), but the Enabled value is still False.I don't know why.Now here is the really interesting part and may give somebody an idea about what's happening: I can change the Enabled value via the debugger (via the Watch) to True.The EventChanged will fire, and from that point on I can set the Enabled value to either True or False and back again with no problems.
I even did some really crazy testing to see if perhaps the debugger just wasn't showing something.
did something like:
Dim idiot as boolean = false
if <logic> then
idiot = true[code]....
I have set the values to Minimum and Maximum, but the problem remains.
I have a RichText control on my form. In the control when running, the tab key does not do anything. I would like to enable it and set the size of the tab. How can I do this?
View 1 RepliesThe issue I'm having is with the text on the tabs in my program. The tabs are set to a fixed size. When it displays the text, it's always centered. But when I add a new tab, the text on the tab to the left of the new one changes to left-align. This just seems odd and random. I feel like it's a dumb question, but how can I get the text on my tabs to always be left-aligned? I'm also curious about a way to put an 'x' button on my tabs. I really don't want to redraw the whole tab though, that usually just looks

View 7 RepliesI want to enable the 'ReaderMode' for paning/scrolling my control in .Net. Closest thing I found was this Win API function .url....However, I'm not sure how to call this one, in the documentation it says, This function is not declared in any public header. To use it, you must access it as ordinal 383 from Comctl32.dll.I've never called a function that didn't have a name before, can anyone describe how to do this in VB.Net?
