• Visual C# Inserting Image in my Report (ReportViewer)

  I finally have an understanding of how to create simple reports from my dataset using the ReportViewer. I now wonder how I can make custom (SQL-queries) on my dataset that will fill for e.g. a table. For example I have a picture that I like to insert into my report. That picture do I store as a string in my database. (In my program I do have conversions functions for: Image -> byte[] -> string -> byte[] -> Image). I'm assuming that your DB string is the path to the image.  If so, in your report's picture control's Value property, do something like this: =" file:/// " & Fields!PictureSrc.Value Whe ...Show All

• Visual Studio Interactive Multi Column Sorting question

  I know that you can do interactive multi column sorting, but in what sense   That is, lets say I have a table with a State and a FullName column.  I realize I can set things up so that the user can sort on the state column, or the user can sort on the Fullname column; But is it possible to fix it so the user can sort (interactively) first by State and second by FullName   If so, how does it work   Does the user click and ctrl-click various column headers Well, that's one of the frustrations of using a product like this.  Because it can be used in a variety of c ...Show All

• Visual C++ Unmanaged allocations in mixed code

  I am writing application using C# UI level and C++/CLI libraries which internally work with legacy unmanaged C++ code. Making stress tests I found that after long time unmanaged memory allocations (C++ new) fail because there is no memory available. My guess is that GC is too lazy to make collection, so it allows to managed objects to take all available memory. So I added GC.AddMemoryPressure call for every new operator, and GC.RemoveMemoryPressure call for every delete operator. However, it didn't help, and application still crashes in situation when unmanaged application successfully works. What else can I do Is there any way to contro ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MC2 Editor

  I can not see the MC2 Editor being part of the XNA project. When I build/rebuild MC2 the editor files are not updated. What do I do wrong or How can I make changes and updates to the MC2 editor Correct, the editor project is not part of the XNA build projects because Visual C++ Express cannot build them as they require MFC. If you have Visual Studio Standard or Professional you can build the project with no problems. In the Source\Editor folder you will find the projects for building the editor code. Compile both of these: EditorMFC.vcproj and Editores.vcproj and you should be set. Thanks! ...Show All

• Visual C# windows messages

  How can i learn windows messages... like mouse move keydown.. When the mouse mouse what is windows sending to my app is there some article about this There are not much information in .NET articles and books if you want to learn Window Messages (WM), you need to dig to various Visual C++ books and articles on pure Win32 Windows Programming  (Not MFC) to learn these stuffs. The more you understand Windows, the more you will get to know Window Messages. MSDN online has nice set of articles regarding this subject, but are pretty complicated for beginners.

• Game Technologies: DirectX, XNA, XACT, etc. Vertical Sync in Managed Direct

  I am experiencing a tearing effect on the edge of objects which are moving. This seems to me to be the classic problem which vertical syncing was designed to address. The idea being you syncs each frame to one refresh of the monitor. So you in effect lock the FPS to the monitors refresh rate. How do I implement vertical sync in Managed Direct X. I have scoured the web and MSDN. I have found references to it in Direct 7 using the C++ interface, but not Managed DirectX or even Direct X 9. Is there some better way of stopping the tearing effect I am experiencing. Also how do I cap the frame rate, as my app at 250 fps is very smooth ( ...Show All

• Visual Studio Express Editions 3d games?

  Well. you know if I creat a 3D graphic, is it possible to "move" then render the graphic in real time with Visual Basic Express or are there easier solutions to make EASY 3D games Thank you! Keehun Nam If you would like to start writing games in VB.Net and Managed DirectX I would start hanging out and using the Windows Game Development forums on this site. In regards to using VB.Net in 3d applications lots of people are doing it and it can hold it's own, remember that when you do write applications in any of the .net languages they will run the same.

• Visual Basic Control Y !!!

  What have you people done to Control-Y For the past 10 years that I've used Windows this meant REDO (opposite of UNDO). In VB2005 it deletes a line. SERIOUSLY!!! not funny. Control Y deleting a line pre-dates windows. (I remember it from wordstar back in 1983) That being said it is likely that you have chosen a profile which had these mappings. You can change them or pick a new profile. Tools -> Options -> Environment -> Keyboard Mapping scheme. Hope that helps... ...Show All

• Smart Device Development How to list all DLLs and unload one thats not listed

  In my target device there are 13 tasks. One of them is called services.exe and runs my DLL (httpadmasp.dll). Everytime I surf to a certain webpage located on the Win CE device (hosted by it's webserver), it runs the DLL so I can't replace it after I recompile without rebooting the Win CE device. Is there any way of freeing my DLL in some other way Killing the services.exe task kills all services. If I try to run services.exe from the commandline afterwards it asks for parameters which I don't know how they should be set. How do you get all services back up I think a soft reboot might do it but I don't know how to do that on my device. The ...Show All
