• Visual C++ Can you use C++ dll files in C#?

  The title probobly isn't very descriptive, but that was the best I could think of :\ I've noticed that the 3 managed languages (VB, C#, J#) can all "assimlate" eachother. That meaning, you can, say, create a .dll file in any language, and reference it in any of the other languges (which I know at compile-time or whatever, it converts the .dll to the native language instead). But, is this possible with Visual C++ I've seen a few threads of how people can use C++ .dlls, and then use them in their C# applications. So, how would you go about this Do you have to create a managed C++ application And/or have to tinker with the .dll's assembly, or something Thanks. EDIT: Also, is using a, say, C# .dll file in a C++ application possi ...Show All

• Visual C++ Link Error

  Hi all. Im having a link error when i compile 3 source files together. error LNK2001: unresolved external symbol __imp__SendMessageA@16 Thats just one out of 4 errors. I've googled the error msg and found that other have had the same problem, but neither of their problems were ever resolved( at least not on the article/forum) So since i have this issue and i'd like to know what i need to update/change to fix this error. Im using VC++ 6 platform SDK 2003 Everything is in order to compile in the settings etc. From what i've read its some sort of out-dated problem. But how can it be out dated if i can compile the source by itself It would'nt compile if it was so out-dated right Any suggestions on what i should do is appreciated as always. ...Show All

• Visual C# How to edit ico files in the solution?

  When I double click on my application icon in solution explorer, it comes up in MS Paint, not in VS.net's icon editor. I checked file associations, and ICO files were not associated with anything, so I set them to VS.net -- made no difference. Tried Open WIth.. "Resource Editor" (Is that what the icon editor is called ) get modal message box "This file cannot be opened with the selected editor".

• Smart Device Development Customized datagrid column won't change colors of unseen rows when scrolled

  I was trying to change background colors of specific rows of my datagrid following this suggestion:   http://blogs.msdn.com/netcfteam/archive/2006/04/25/583542.aspx My application is an inventory counting program and I want to change colors of a rows by their specific value of a column (in this specific case, "DateLastCounted" column).  It worked fine except one problem. My datagrid has vertical scroll bars. When I ran the code, the rows of first screen showed exactly what I intended but when I scrolled down, background colors were never changed in any rows which were supposed to be changed.  I walked through codes in debug mode and I couldn't find any problem: It means every line in the overridden 'Paint' methods w ...Show All

• Visual Basic How does the Windows Screen Saver detect whether the user has used the keyboard or mouse?

  Hello all, I have posted a similar question in the past but the answers that I got weren't too helpful so I thought I'd give it another shot. How can I, using VB.NET 2003, detect whether the user has used the keyboard or mouse much like the Windows Screen Saver needs to do before it starts up. Thanks in advance. N. Farr Use the mouse events and the keyboard events in your application to throw a flag iondicating wether it was the keyboard or the mouse that caused activation ...you can also use a timer to start another process if the keyboard/mouse activity was not detected ...in other words every time you set your flag you also start/restart a timner and if the timer reaches a certian time do s ...Show All

• Visual FoxPro Help me ! How to add controls to Pageframe at runtime ?

• SQL Server SSIS and the Receive Command

  I built a system where I am sending batches of messages using a single conversation. I want to pull these messages out of my queue using Service Broker. I may have more than one batch sitting in the queue waiting to be picked up, so.... In my SSIS package i started by getting a unique list of conversation_handles where the message type is my end of batch message ( should only be one per batch). Then I used the foreach loop construct thinking I could pass the conversation_handles around and into the data flow. In the data flow I want to pull all of the messages at once. It looks like the receive statement is designed to do this with the concept of using a table variable. So I built this SQL to use in for the SQL Command of my OLE ...Show All
