• Game Technologies: DirectX, XNA, XACT, etc. can i use visual studio .net professional?

You're pretty much unrestricted for Windows development. You can't expect the same for development on a console when what you write isn't going through certification. ...Show All

• Windows Forms Mouse wheel left/right click ?

  My mouse wheel can click left and right as well as down. Does anyone know how to capture this event It doesn't fire the mousewheel or mouse click events. I also tried WM_SCROLL.

• Smart Device Development How can I download doc, jpg and other files to PDA via CF.Net?

  Hi all, I really need some advice here - I'm developing a PDA app in Cf.net 2.0 with SQL Server 2005 on the server. The app allows medical professionals to take selected patients data with them when they go out to consult or to hospitals etc and as part of a patient's record there could be associated documents (say, referrals or letters from another doctor or text files or even JPG's/BMP's of xrays, etc) and what I need to do is when the user syncs with the server (via my CF.Net app) those files should be downloaded to the PDA so they can be opened there - so a .doc file will open with PocketWord for example. My problem is literally how to do this! ActiveSynch does this stuff automatically if you copy a file manually but I want to downlaod ...Show All

• SQL Server Loading data from xml

  I have an xml file I want to use as the source. It's not overly complicated, but not simple either. It has one hierachy, and one optional field and looks like this a 1 'text' 2 'text' b 1 'text' 2 'text' 'optional field' Ok, now I want the data to load like this: a,1,text a,2,text b,1,text b,2,text, optional field but when I try to use the xml source it won't create the xsd...anything I can do The error message is at the point when I hit the button to create a schema. Up to that point I'm simply pointing at a fairly simple xml file (part of which I've copied below. < xml version="1.0" > - < ADB ID =" 1 " > < I ...Show All

• .NET Development Add new record

  I learned how to edit a record, but now how do you add a new record Dim workRow As DataRow = workTable.NewRow() what is a datatable this is my hang up for now Davids Learning Remember a datatable is NOT the database table. But a local variable of type datatable that exists in memory only. If you wish to persist this data in the datatable then you need to run a process by which it will be written to a backing store - whether that be a database table (via a tableadapter) or some other means. What is being suggested is that the you have missed out a tableadapter.update method call which would persist the data table contents back to a database, Without this - the datatable is updated but ...Show All

• Software Development for Windows Vista Sample Grabber misses samples

  Hi All, I'm struggling to work out why the sample grabber sometimes misses samples. I have a filter graph which consists of a DV camera as source, dv splitter, dv decoder and a sample grabber on the video chain through to a video renderer, and the audio chain terminates in a null renderer. I'm using the sample grabber's buffercb method, which includes a double SampleTime parameter. I write a simple callback which basically divides this double value by 0.040 (my video is 25Hz, 40ms/frame) to get a frame number. I'm then just storing this frame number in an array. I'm not doing anything else in the callback, so it's very lean and mean After ~50 minutes of video, I dump the array contents out so i can analyse what frames i receive ...Show All

• Visual Basic The simplest way to catch ALT + F4

  Hello, If you need to intercept ALT+F4 in your program : (Instead of using KeyDown which is just bad ) Private Sub MainForm_FormClosing( ByVal sender As Object , ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me .FormClosing Dim Response As MsgBoxResult = MsgBox( "Do you really want to exit " , MsgBoxStyle.YesNo) If Response = MsgBoxResult.Yes Then e.Cancel = False Else e.Cancel = True End If End Sub thanks for sharing that with the community. Remember, this will also work when you press the close button of the form which has this code in place, implement the FormClosing event with the messagebox, not just when you pr ...Show All

• Visual Studio Express Editions Viewing variables

  Hello   While I'm debugging, even though the variables are fully defined, I can't seem to view them. They aren't recognized. What shall I do   Thanks There are several reasons for this, so you need to give more information. But if you have the program running in the debugger with the symbols in watch and you get the error CXX0017: Error: symbol "xxx" not found there are two things you should do. The first is make sure you got the spelling right, including case. You would be surprised on how many people get this wrong. The second thing to check is to make sure you are running the program in debug more without optimisations. The optimiser can remove variables it can do ...Show All
