• Visual C# Running C++ from a C# app (.NET detection)

  I have a c++ script which detects if .NET is installed and what version. I would like to put this c++ script in a C# .NET app so every time someone tries to start the C# app, the c++ code is run, and then the C# app is started if the c++ code returns true. Can I use the c++ code in the C# project Or does this code need to be based outside the project, and it will have to trigger my C# app My only goal is to give the user a nice Message if they try to start my C# app and .NET is not installed. If someone knows a better way to do this please let me know. Below is the header for the c++ function I want to run. The code is by Aaron Steb ...Show All

• SQL Server 2005 April CTP Install Failure

  SQL Server Setup could not conect to the database service for server configuration. The error was: [Microsoft}{SQL Native Client} Named Pipes Provider:  Could not open a connection to SQL Server [2].  Refer to server error logs and setup logs for more information. For details on how to view setup logs, see "How to View Setup Log File" in SQL Server Books Online. That is the error when attempting to install to W2003 running as a VPC2004 guest OS. The framework and VS Beta 2 are installed and functional.

• Visual C++ Use of HTREEITEM in /Clr

  HI, When compiling an app that uses HTREEITEM i get an error complaining about _TREEITEM - _TREEITEM does not seem to be defined. I am currently trying to see if this will work: typedef struct TVITEM *HTREEITEM; Any hints on how to get around this I can confirm that the use of typedef _TREEITEM {}; solved that problem. I have not tried fiddling with the Lean and Mean def's as it seems inconsistent to do so. If afxcmn.h is included then the typedef above should occur regardless. The code uses #define VC_EXTRALEAN - it is quite diverse, but is mainly client side DBMS using ODBC with common controls. Thanks... - Tim ...Show All

• SQL Server DMX Query

• Visual C++ function malloc()

  Hello everybody int* p; p=(int *)(malloc (10 * sizeof (int) ) ); the above statements tells the c compiler that we wnat to store 10 integer values. it is just like that int a[10]; Means the last value that can go in p[9] if indexing is starting from p[0], just like a[0] to a[9] But in p we are able to store value at location p[10] and even in p[100] WHY For example int *p,i; p=(int *)(malloc (10 * sizeof (int) ) ); for(i=0;i<=1000;i++){ p =i; } The above code runs well in vs 2003 but i think it has to give error at p[10] Please tell what is it happening Thanks In C (and C+ ...Show All

• Visual Studio Express Editions VBExpress2005 - "There is no editor available" with "Unable to open module file"

  I know this has been posted a few times before, unfortunately, none of the 'resolutions' have worked for me. Situation: I am running Visual Basic 2005 Express on a Windows 2000 Pro system (current service packs/updates). I created a program with two forms. Form1 is the main program, Aboutbox1.vb is a Help About form. I created the program, compiled, and it was working great. I published the project, then it happened.

• Windows Forms Tabcontrols

  I have dropped a tabcontrol on a standard windows form. My purpose for the tabcontrol is to hold shipping addresses for a customer. So, if there is one shipping address there is one tab. If there are two shipping addresses there are two tabs. I want to have textboxes to hold the shipping information on the tabcontrol. However, I don't want to have new textboxes for each tab. I want to reuse the exact same textboxes on each tab that is added and simply populate each textbox from the database. Currently, if I run the program the textboxes only appear on the tab on which they were placed in the source code. I need to make the textboxes ...Show All
