• Smart Device Development Picture transmission from Pocket PC to remote server

  Hi all, I need to transmit a picture I capture by my pocket pc camera to a folder exsists in a remote server. The picture often 40 KB size. Witch is the proper way to do this quickly. Best regards... It depends on your connection. If you have reliable LAN, you can access file share on a server directly using UNC paths. For internet you probably should use web server and HTTP post. ...Show All

• Visual C++ Walking the call stack as fast as possible

  Hello ! I have dedicated some time to developing a memory allocator that replaces the default crt allocator. Things are almost finished, but recently i've added a leak trace that saves the call stack for every memory allocation. (The stack is saved in the process memory, so there's no interprocess communication overhead.) That adds a very important overhead to the allocator and i was wondering if there is any efficient way of getting the call stack. At the moment i'm using StackWalk64 and the profiler i'm using (CodeAnalist) reports that 99+% of the time is spent in dbghelp.dll, ntoskrnl.dll and msvcrxx.dll (strangely, the functions used fro ...Show All

• Visual C# Search DataSet

  I've got an app that populates textboxes based on a DataSet, like so: txtModel.Text = ds.Tables[ "dtModels" ].Rows[iCurrentRow][ "Model" ].ToString(); txtDirectory.Text = ds.Tables[ "dtModels" ].Rows[iCurrentRow][ "Directory" ].ToString(); txtName.Text = ds.Tables[ "dtModels" ].Rows[iCurrentRow][ "Name" ].ToString(); etc.... And I can navigate through this DataSet by changing the row index, no big deal.  But I'd like to have a search box that the user can put a string in and the dataset would only return those records LIKE the string.  In other words, if I enter 'C130', then the DataSet would set it's filter for ...Show All

• Smart Device Development application does not appear in 'Remove Programs'

  with VS 2003 I used to build the CAB files manually. Now I'm using VS 2005 and I'm trying to build a CAB file with it's built in process. I've managed to build one and installed my application. But I'm not entirely sure what i need to do in order to create a shortcut to it in under 'Programs' and dont know how to make it appear in 'Remove Programs'. Thanks. No, that should not matter either. Unless installation completely failed (because of security restrictions or for any other reason) and application was never installed. Naturally, application which is not installed won’t appear in “Remove programs ...Show All

• SQL Server Datareader Query Timeout

  Hello, I am running a query via a ado.net data flow source. It works great for a small number of rows, but if I try to execute a long running query it times out with a communication error. I have looked through the doc and every property sheet that I can find in my package, but I can't find anywhere that a timeout is specified. Any help on finding this would be appriciated. The query is running against DB2 on z/os and I know it is timing out on the server side because I can watch the query run on z/os and it continues to run after SSIS gets the error. Thanks! Harry I am having a similar issue to this that I cannot find the answer ...Show All

• SQL Server Unexpected function sequence error when using SQL_CO_FFO on stored procedure

  Hi all, In my ODBC program, I try to execute a stored procedure returning a unique result set, by using a fast forward cursor (SQL_CO_FFO), but I get a "Function sequence error" when fetching the first row. FFC forces the ODBC driver to use sp_cursoropen, which is fine for me because I need multiple active SQL statements. I appears that the content of the stored procedure matters. When the procedure implements only a simple SELECT statement, it works fine. But when adding a simple SET statement or even a IF block, I get the sequence error! This is really not expected. I get the same problem with SQL Server 2000 and 2005 ...Show All

• SQL Server How to get SQL Server 2000 data files location?

  Hi. Is any way to get SQL Server 2000 data files location using TSQL Thank you for your answer. I have already considered this variant, but using a little other request: select top 1 filename from model..sysfiles. This is not very simple approach, becase then one must parse the path name and remove file name part at the end. Well, if it is the only way to get result, I'll use it. ...Show All

Any help is much appreciated, or a point in the right direction. Oh, im trying to do this with sprites. You may need to tinker with your presentation parameters.  I wanted to do the very thing you are attempting to do now; and after a few struggles, figured out that my main problem was that I wasn't using alpha colors in the Draw2D function of the Sprite object.  However, apparently the color values aren't the problem with your source code.
