• Visual C# how to overload a native function

  Is it possible to overload a function from VS2005 IDE If so, I want to overload graphics.drawline() which signature in CF is drawline(pen, int x1, int y1, int x2, int y2). I want to change it to drawline (pen, point A, point B). Any help No, you cannot modify this class in any way. You have to write some sort of a wrapper/helper class.

• Visual Studio Any tutorial for GAT?

  I am wondering if there is any good tutorial available anywhere that would describe how to implement typical guidance scenarios in guidance packages from the beginning to the end Materials that I found so far are not satisfactory for the following reasons: 1. The latest Hand-on Lab seems to be created for the Dec 2005 version of GAT and cannot be registered with Jun 2006 version; 2. Most articles either describe the theory without specific examples or give specific examples of small tasks without describing a big picture; What I am looking for is a specific roadmap from A to Z starting from generating a stub for a guidance package and continuing with specific steps required to implement a scenario until the package is successfully ...Show All

• .NET Development SqlConnection State property mistaken behavior

  Hello, I don’t know if this should be like this, but if so it is bringing some problems that I think could be common for everyone which works with remote database servers. I have a regular client – server system which has several windows applications on desktops communicating with a data server which supports my shared storage and database. The situation is that network is very poor and fails constantly. When I start my application I can accomplish connection but sometimes in the middle of the day the network is down. The problem is that after make the first connection this one stays pooled and later when I try to open it, everything appears to be fine, I check connection state and the result is open, ...Show All

  I set up a doc/view structure by VS 2005. I also use Formview. I want to get a HDC of a 'picture control' window on the formview.

• Visual C++ calling sleep in header function causes wrong thread to sleep

  I'm experimenting with the BackgroundWorker and have a problem. If I use the Sleep method inside the dowork method the thread correctly sleeps, but, if I put the Sleep call in a function defined elsewhere in the code the main form sleeps. Does this only depend on the position of the call Is there a way to avoid it The sleep will be performed on the thread that is calling it. If you put a breakpoint on that line, you should see the thread calling it. Whether it is in a header function or somewhere else isn't relevant. ...Show All

• SQL Server Subreport throwing an exception when placed in a group footer

  I ran into this a few weeks ago and found that several others had as well, but no one had yet found an answer. I found the answer (at least one of the answers) this weekend and wanted to share it. I had recently added a subreport to a group footer in a table and started getting an error. Depending on the data, the error wasn't always present. I didn't have a problem when I moved the subreport to any other area in the report. Here is the error I was getting: An error occurred during local report processing An internal error occurred on the report server. See the error log for more details. It was a local report (rdlc), so naturally, there was no error log <g>. I added an event handler for ReportError and collected this inf ...Show All
