• Visual Studio Express Editions SQL Server Express

  I cannot install the latest release.  It says I have prior releases still installed.  The uninstall tool also says I have installed releases, but it will not uninstall them either, it gets errors and fails.  None of the products show up on the add/remove list as I ran the uninstall on all of them.  How do I correct the problem, why doesn't the tool remove them   If it can detect them, you would expect it could remove all the components it finds one way or the other. I am having a similar problem. The error message I get when I try to use the auto uninstall programme is: The action is ...Show All

• Visual Studio Tools for Office Can I save information inside a Word Document

  Is it posible to save information in a Word Document, in a a way the user can’t see it or edit it, but i can read it or modify it using code Thanks Hi jalekz, If you want to do it using VSTO framework, you could use the Data Island to cache your information. You will find a good description here: Caching Data http://msdn2.microsoft.com/en-us/library/75akte27(VS.80).aspx   This would be an example on how to have a field that caches a name in the document's data island:   public partial class ThisDocument { [Cached()] public string name;   private void ThisDocum ...Show All

• Visual Studio Express Editions GDI+ Mapping Question

• Visual C++ C and C++, how do they differ from each other?

  Hi there, One of my friends is NOW asking me to explain the difference between C and C++. Let's assume that we have a code below; #include <stdio.h> int main() {     printf("Hello World!");     int i;     int j;     int k;     return 0; } This code can be built as C++.  However, it cannot be done so as C. I tried it with Visual C++ 2005 Express Edition. This tool is very famous for its most advanced compiler. Is this true Does the tool support  the C99 spec If not, plz let me know the  difference between C ...Show All

I'm trying to get the sqlite3.dll working with my programm. This is my code: #define sQliteDLL __declspec( dllimport ) int feedBack; sQliteDLL typedef struct sqlite3 sqlite3; sQliteDLL int sqlite3_open(const char* filename, sqlite3 **ppDb); sqlite3 *db; feedBack = sqlite3_open ("test.db",&db); What I understood so far: I need to create a prototyp of my function etc. with the dllimport-thing to tell the linker where to look for the code of those functions. After that I can use the function ...Show All

• .NET Development WebClient.DownloadData times out

  I have a C# program (.NET v2) that reads a web page based on information I send it. I do this several thousand times. Sometime shortly after I start (maybe 10 minutes) I get a message that says "The operation has timed out". I am assuming this is from the server side.
