• Visual C# Why does Visual Studio 2005 starts to consume 100% of my CPU?

  Hello, Sometimes Visual Studio 2005 starts to consume 100% of my CPU. I've tried see if it is when I'm doing something specific, but I cannot put my finger on what it is that might trigger it. It is my first solution in VS 2005, so I have no clue if it's specific to this C# solution. I have a Windows Forms project and a Webservice project in my solution, all connected to a SourceSafe 6 database. This far I've always been editing the Windows Forms project when the CPU consumption has kicked in. I don't even have to build or run the solution for this to happen. If I close VS 2005 and open it again everything will be normal, sometimes only for 5 min, while other times it may well pass an hour without it happening. I no ...Show All

• Visual C++ 'out' value-type parameters and managed/unmanaged references

  WOW the area of tracking references is confusing. I have a large unmanaged COM server (C++) to which I'm adding managed interfaces. Many of my methods provide output-only value results. For example, my Image class has a method that in C or COM you would declare as PixelRange(double* pMin, double* pMax), and in C++ you would declare as PixelRange(double& min, double& max) and in C# you would have PixelRange(out double min, out double max). It seems that I must declare this interface in managed C++ as PixelRange([Runtime::InteropServices::Out] Double% min, [RuntimeInteropServices::Out] Double% max). My problem is that for each such parameter I have to create an unmanaged variable to pass to the internal function, and I have to ...Show All

• Visual Studio Express Editions How to debug DLL?

  Hi, I have a dll written in C++ (6.0 MFC). The functions of this dll is called by an application I just started in C# 2005 Express edition. I read about how to call a dll in C#, but my problem is the reverse situation. I need to debug the dll to find out if all parameters are passed correctly from C# to the dll functions. But if I set the exe file compiled from the C# to test the dll, it does not even start (it does when I start outside of the C++ debugger). What is wrong and what can I do I would be grateful for any help. Peter I tried VS2003 and chose Native Code. This is what I got: (Disassembly cannot be displayed in run mode.) I more or less gave up on VS 6.0, tho ...Show All

• SQL Server Return Top row from a ResultSet - SQL Server (TOP)

  Hi all, I need to return only the top row of a ResultSet that is generated from my Query but can't seem to find anything in SQL Server 3.0 Mobile that allows me to do that. I know in SQL Server (Desktop) I could use the TOP keyword. The query I have is as follows, and just need the top row. Now the returned resultset will, in time, be massive, and there is just no way I can afford to return this amount of data in my application only to take to the top/first row. The query I have is as follows... SELECT * FROM tbl_NSP_AnswerSet WHERE (DateCompleted IS NOT NULL) ORDER BY DateCompleted DESC (I want the last record that was inserted into the database) Thanks The suggested solution only seems to allow for "TOP 1" queries. But ...Show All

• Visual C++ Unable to find an entry point named 'HidD_GetHidGuid' in DLL 'HID.DLL'.

  I want to use the HID as a driver to communicate to a simple peripheral. When I call the 'HidD_GetHidGuid' function I get the subject error. If I run 'dumpbin.exe' on the 'hid.dll' the entry point is there with that name! I'm using the 'hid.lib' in 'winddk\3790.1830\lib\w2k\i386' in the linker and it builds okay. If I run 'dumpbin.exe' on 'hid.lib' the exported names are listed are decorated. I would understand if the error listed the decorated name '_HidD_GetHidGuid@4' as the name that couldn't be found. I have the include files 'hidsdi.h' and 'hidclass.h' bracketed with 'extern "C" {}'. I get no errors or warnings when I build the project. I'm really confused. Hello Re: Unabl ...Show All

• Visual Studio 2008 (Pre-release) Seeing the Mesh within Geometry3D.

  I am new to this whole '3D' thing and am having a tough time visualizing some of the stuff I have created.

• Visual Studio 2008 (Pre-release) Reading and Writing image "Rating" metadata

I'm able to read the rating although I noticed that the rating is written in several places in metadata... and I'm not sure which Vista is using... it looks like all of them are changed at the same time and are kept in sync... so do I have to modify all of them to keep them in sync /xmp/Rating / xmp/xap:Rating /app1/{uint=0}/{uint=18246} When I'm trying to modify the rating... nothing happens...

• Windows Forms Multiple Lines for DataGridView Header Text

  Anybody knows how to manually break column header text (in DataGridView) into multiple lines Ex: address line 1, I would like to see "address" in one line and "line 1" in another line. If I let the program auto break it, you would see "address line" in one line and "1" in another line, which is not something I like to see. Any help or pointers are appreciated. Bo Hi, The '\n' trick works for me. Set the WrapMode to true and resize the column width, and you can have a look whether the column name goes to the second line. Hope this helps. ...Show All

• Software Development for Windows Vista Packaging: "[Content_Types].xml" part?

  I'm messing around with the packaging APIs (my eventual intent is to figure out how to add my own custom parts to an existing XPS file, since MS isn't telling). I started with the PackageRead sample, and made some adjustments to basically take a .XPS input and dump it to a flat-file structure. I'll know when I have it right when I can take any of the sample XPS files, dump to a folder tree, manually re-Zip that back to a .XPS and get a faithful reproduction. It's mostly working, except some sample XPS files have a [Content_Types].xml file in the package root. But for whatever reason, none of the Package collections (Parts & Relationships) seem to recognize the existence of this. So I have two questions: 1) Anybody know how to get at th ...Show All
