Replacing The Tab Control's Tabs With Custom Tabs Made In Photoshop
Mar 16, 2009I 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?

Oct 1, 2008I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

Making The GUI A Scrollable Window - Tabs Get Built, Displayed And Disposed As The User Scrolls Left And Right Through The Member Tabs?
Mar 6, 2009My 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.

View 5 RepliesPassing Values Between Tabs In A Form In 2010?
Jan 1, 2012I 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
[code]....
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
VS 2008 Preload/execute Tabs On A Form?
Jan 14, 2010I 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.

Forms :: Change A Property On Form - Doesn't Show That Change
Jan 13, 2010I'm working on a simple base form in which all the other forms in the project will inherit. This base form only adds 5 properties (at the moment) dealing with painting a gradient background. The problem I'm facing right now is when I change a property on Form1 (the test form) and click run it doesn't show that change. I also checked the .designer.vb file and when I make a change it's not added to the code behind file, I'm at a loss right now to why.

Assign To Variable If Inherits From Class .NET 2.0
Mar 31, 2009I think I remember reading somewhere that it was possible to assign items to a variable if the item inherited from a base class, but I can't remember how.
I want to have a class that gets properties set and one of the properties is an error code property. I want to assign any exceptions that occur to the property, but it could be any type of exception. I remember that all exceptions inherit from the Exception class.
How can I assign an exception to a property based on the class it inherits from?

How To Store An Instance Of A Class Which Inherits From NameObjectCollectionBase In Settings
Nov 30, 2010I have created 3 classes which inherits from(System.Collections.Specialized.NameObjectCollectionBase)
The first class "SQLCommandsCollection" stores "SQLCommands" in a collection.
The second class "SQLTableNamesCollection" stores "SQLCommandsCollection" objects in its collection.The Third class "SQLDBNamesCollection" stores "SQLTableNamesCollection" objects in its collection.
Ultimately I will sit with a "SQLDBNamesCollection" collection which contains all Table names and its respective SQLCommand objects.
I would like to store this "SQLDBNamesCollection" object in my.settings("QueryViewerQueriesPerTableNamePerDBName")
at runtime but I am unsure what this settings type should be.
I have tried system.oject but this does not seem to work as I get an "Unable to cast object of type 'System.String' to type 'Fusion.SQLTableNamesCollection'" exception when I try to retrieve from settings. See below code.
