• Visual Basic clearscreen()

  I want to clear the user typed content of a textbox and the results which appear in labels as a result of the code in my command button. I thought I could create a command button, label it btnClearScreen and code it ClearScreen() however, when I do this, VB.Net tells me that ClearScreen() is not declared.  I thought I read that ClearScreen() would clear data on a form but not save it.  I take it ClearScreen() is not a built in (method) ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX messes up other Threads!

  This is my situation: In my app I create a new form that renders directx things (simple meshes...)... The DX (DirectX Feb 2006) form starts up it's own render loop, which runs until the form is disposed. On another thread I run a control that displays a graph... When adding points to the control it calculates the DateTime value to it's internal format and then displays the form. If the DX form is disabled (not even loaded) the graph wor ...Show All

• Windows Forms graphics flicker problem (double buffer not working)

  I am trying to create a simple Breakout type game. I have a game panel on my form that holds my game (the paddle, ball, and board of blocks).

• Visual J# Why is these text comparisons not working

  In my little program I have a richtextbox and a button. When clicking the button this code is run and when I debug I see that my in the richtextbox entered text is indeed in the txt variable.

• Visual Basic Using ContextMenus with AxHost'ed ActiveX Controls

  I am upgrading from VB6 to VB.NET. I place a third-party ActiveX control on a VB.NET form. I cannot set a ContextMenu for the control because AxHost does not support it.  (I can set the property in the start-up code but nothing happens when I right-click.) Instead, I handle the MouseDownEvent for the control and call myContextMenu.Show(controlname, point). The context menu pops up as expected. When I move the mouse up and down the list of i ...Show All

• SQL Server Passing Multivalue Parameters Through a Report Link

  I've created a line chart in my report which lists number of transactions by month. I've also created a report to list transactions by day. My goal is for the user to select a month and link the report to the graph with the selected month divided up into days (in other words, the user wants to see the number of transactions for each day in the selected month). Anyway, everything is working perfectly except for one thing. In the list of parame ...Show All
