• Visual C# #define INT_SIZE int32 support?

  I have a counter that I need to easilly change between int16, int32, int64, float, double, etc when needed. In C I would use a define, but here I can not. I've looked into generics but that won't do because I need to be able to increment the int value and with a struct-generic input for the class that won't work. So how can I do then I tried using int btw but that made it so darn slow! "I need to easilly change between int16, int32, int64, float, double, " When does the type change should take place Ar compile time or at runtime ...Show All

• Visual Studio Express Editions Issues with sub and dim

  OK, I'm trying to create an application that writes a large amount of data to a file. But because there's a good amount of data (and certain sections are quite repetative), I'm passing arguments to a subroutine that has an "outline" of the basic data, which modifies a portion I specify. Here's an example: Private Sub Button1_Click(ByVal sender As System.EventArgs, ByVal e As System.EventArgs) Handles Button1.Click Dim inputio As StreamWriter = New StreamWriter("test.txt") Call writeit(22, "FOOBAR", 10) Call writeit(26, "JACK", 15) Call writeit(30, "NIGHTMAN", 18) Call writeit(34, "UBERNOOB", 22) inputio.Close() End Sub Private Sub writeit(ByVal color ...Show All

• Smart Device Development Breakpoints causing connection loss on debug

  What started out as a random problem has become a full-time issue. Attempting to run a WM 5.0 app causes a "The Connection to the Device has been lost, blah, blah, blah" error. Deleting ALL breakpoints allows the app to deploy and run perfectly. Breakpoints can then be set for debugging. Setting a SINGLE breakpoint before deploying, however, will now cause this problem. The larger the app became, the more prevalent the problem became until some critical point was reached...now it happens every time. VS2005 and ActiveSync have been removed/reinstalled. I've tried VS SP1 Beta and ActiveSync 2.5 Beta. I've tried several different devices along with the emulators. No change. Has anyone heard confirmation of this ...Show All

• Windows Forms Datagrid index problem

  I have a master/child datagrid. Both grids are bound to dataviews. Everything works find until I introduce a rowfilter on the dataview for the master. I can see the data but I get an argumentoutof range exception for the index paramater when either I change page or select a grid item. What gives here Can anyone point me to a decent article on what needs to happen Glad you solved the first problem. For problem #2, I'm going to recommend you post it to the WinForms Data Binding forum. It sounds to me like the issue lies more in that territory than ADO.Net itself (and I'm not as familiar with Data Binding). Post a new message thread there, since sometimes messages with a lot of responses don't have very ...Show All

• Visual Studio Team System Strongly Typed DataSet analysis

  Hi, It appears that VS2005 Code Analysis ignores the code in strongly typed datasets, probably because of the GeneratedCodeAttribute on the class. Is there anyway to force my partial class code or ideally, all of the generated code to be analysed I understand that some stuff in the auto-generated dataset code will violate CA rules but picking up naming issues and ensuring my extensions are valid would be very helpful. I've considered hand removing the GeneratedCodeAttribute from the .designer file but it will only be replaced when the file is regenerated from the source .xsd during a build. Thanks, - Jason You can find out a little more about these new features in Orcas, by reading the following post: ...Show All
