I have buttons a few text boxes etc on a form, however I want to move it all to a tab (as in the tab control). I add a new tab control, cut all the buttons and textboxes, paste them into the tab control on tab 1. All good so far. When I run it, and click the buttons, they dont do anything. Do I need to move all the code to somewhere else or something?

Well, this time my target is to add and rename Tabs with tabcontrol, e.g.
I have a form and have added a TabControl to it and in the TabPages i have added RTB's,now i have also added a button which should add a new tab page to the TabControl, the thing is i know how to add a NEW tab but i also need to have a new RTB in each New created TabPage and after i create a new TabPage i wanna add the Title of that New TabPage. To add New Title to the New TabPage i have created a New Form in which i placed a TextBox so that that text that i type Into that TextBox should appear as the New TabPage Name.
Here's some code i tried, and i know that there's missing something and i know that the code may be written wrong but that's all i know, unfortunately?
Code:
Private Sub AddNewTabTool_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddNewTabTool.Click
Dim rtb As New RichTextBox

What I'm trying to do is emulate something that we have in C++ in Visual Basic. I have a large table of 25+ columns that I need to display in a grid (don't want a scroll bar). I'd like to use a DataGridView instead of a nightmare of textboxes and add "tabs" to a datagrid view. Lets say the initial tab shows columns 1 - 9, Tab 2 shows Columns 1 - 5 and 10 - 15, tab3 shows 1 - 5 and 15 - 18, etc....
View 13 RepliesUsing Visual Studio 2005 (vb.net) (windows forms) on Windows XP, I have a standard Microsoft TabControl.A button click adds/removes an image from 1 of the Tabs.Seems like the image is placed OVER my tab's text, making it unreadable.Why isn't it like it should be: Image on the left. Followed by text on the right.Why is the image being placed OVER my tab's text? Do I need to do some kind of "refresh" or "redraw" before it will appear as it should? I don't see any way to "make the image appear on the left edge of the tab". (NOT the tab-page.) ... and then place the text just to the right of the image. (Just like a normal image+text tab can do.)The code is pretty simple, it just gets an image from my ImageList: cfgTab.ImageKey = "PadLockClosed.png"' Show CLOSED PadLockThe tab's text changes from: This is my tab text to: T(IMAGE HERE)is my tab text The image appears OVER the beginning of my text. But if I move to another tab, then move back, the image appears in the correct position:(IMAGE HERE) This is my tab text
View 1 RepliesI have a TabControl on a UserControl. I want the UserControl to behave like a TabControl as usual (it contains only the TabControl and a Contextmenu), including Design-time behavior.I have spent the last two weeks finding out how to add the Design-time behavior and I think I have come a far way.The problem is with adding TabPages during Design-time (while the UserControl is a custom tabcontrol, it is using regular windows forms TabPages).In the Designer class, I have the following code to add a TabPage:
vb.net
Dim dh As IDesignerHost = DirectCast(GetService(GetType(IDesignerHost)), IDesignerHost) If dh IsNot Nothing Then Dim i As Integer = tc.SelectedIndex Dim name As String = GetNewTabName() Dim tab As TabPage = TryCast(dh.CreateComponent(GetType(TabPage), name), TabPage) tab.Text = name tc.Controls.Add(tab)
[code]....
So it would add the control to the TabPages collection if it was a TabPage, and use the regular routine otherwise.
(I'm now using 'tc.Controls.Add(tab)' again instead of 'tc.tabCtrl.TabPages.Add')
But, I don't think the designer even gets that far because it is telling me I cannot add TabPages to my usercontrol, because only TabControls can accept TabPages... How can I make my usercontrol understand that it is a TabControl (without Inheriting from a TabControl?)
I 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 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.
I am trying to display an usercontrol(has several panels one on top of the other panel) on tabpage. I am using below code to achieve this.

View 5 RepliesI have a template form with a tab control. How do I change tabs on the form that it inherits from? Do I need a different technique?
View 7 RepliesI have a form with 3 tabs: one tab is for user entry and computations, a second tab shows values that will be used for computations which are read from one database (I call it settings in that the values are constants for calculations but it's not application settings in the way people think of it, to be clear) and the third displays a table from another database. The second tab has a table adapter interface for the dataset that contains values used for calculations that can be changed (to do different scenarios.) Those numbers are read from a single record in a database that has 20 fields and was read once when the data is loaded into the second tab to be displayed.
The problem I am having is that I would like to use the numbers from the second tab (the constants) in computations to be shown on the first tab. I have tried declaring the variables on the second tab as public but they are already "friends" with the form event. However, when I go to use them in calculations, it's like they don't exist.
For example, one calculation I am doing is fuel cost. The user enters miles and this is stored as a variable called mileage. To calculate the result fuelcost, I have to use two other fields that are shown in the second tab: MPG (miles per gallon) and fuelprice (the price of gas). So fuelcost = (mileage/mpg)*fuelprice. These are read from a datatable called testdata which is actually part of the project. I want to be able to use these variables throughout the program but declaring them as public isn't working.
How do I make the variables from one tab usable elsewhere in the program? The other thing I noticed is since the values of the variables are loaded into textboxes and assigned variable names by naming the textboxes, using val([variablename].text) isn't solving the problem either. For example, saying milespergallon = val(mpg.text) is not doing the trick because I am getting a message that 'text' is not an integer when I declare milespergallon.
Update Here the code that is being used:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim mileage = Int32.Parse(Miles.Text)
Dim rate = 0
Dim baserate = 0

TabPage2 is where the variables are displayed that I want to use in TabPage1.
Private Sub TabPage2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabPage2.Click
End Sub
I start my program with a splashscreen and as soon as the mainform is loaded, databases are loaded and data is crunched it shows the form with everything on it. All very nice. But now comes the trick. The form has a strip of 5 tabs on it. The active tab is shown and directly accesible but as soon as i click on the other tabs it needs time to draw everything and calculate its content. And when i have clicked through all of them everything is finally up to speed. How can i speed things up in such away that all this predrawing etc is done in the background just as i got it to work with my mainwindow and its first tab?
I have this in the load sub:
For i = 0 To TabControl1.TabCount - 1
TabControl1.TabPages.Item(i).Invalidate()
Next
But some how this does not do the trick.
I've got a spreadsheetgear form but when I change its values and do some calculations on differed tabs. I want to be able to save all the data and tabs at it curent state so when I open the application it is at the saved state. I'm not worried about the values before I saved.

View 4 RepliesAs Autodesk is going to discontinue VBA for their Inventor product in the near future I have been looking at other ways to run VB.NET in Inventor. To date it doesn't look like VSTA will be the replacement. Automation from an External VB.NET app is certainly possible, but leaves something to be desired for speed and integration. Compiled Add Ins are the Cadillac of choice but can be a royal pain to debug and develop. Autodesk now provides a lightweight VB.NET script interface called iLogic. It's main purpose is to allow extreme customization of Solid Modeling parts. The code actually resides inside the Part Model file.

View 5 RepliesIs there any way to add a C# Web Form to an ASP.NET 4.0 Web Application that is written in VB.NET? I had an ASP.NET 2.0 WEB SITE that I recently converted to an ASP.NET 4.0 WEB APPLICATION. It was mostly written in VB.NET with a couple pages that had C# code behinds.
I've read the following article (the end section about mulitple languages):
[URL]
But it does not seem to help for the following two reasons
1) When I converted my site to an application, it didn't seem to add an APP_CODE folder at all
2) I'm not looking to just write a simple class, I actually want to be able to add a WEB FORM with a C# code behind
When I try to add a new item and I select which type of item I want to add, I am only given to option to add a VISUAL BASIC web form.
I have a workaround right now. If I need a new web form with a C# code behind, I take one of my old C# web forms and just copy and paste the form and C# code behind into the project and then rename it and change the class name as well. Then i make my changes and do what I need to do. It seems to work, but I was just wondering if there was an easier way.
You might wonder why want to put C# forms in my VB app. I wrote my app in VB (not well versed in C# but I can read it). I have a programmer working for me that is much more efficient with C#. I don't really have the budget to spend weeks/months getting her up to speed with VB
I'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?

i could copy the code, exit runtime, go to design mode and paste it into the form myself but because i want to do this for several subs for a lot of forms then it will become very time consuming.
