Hey Chris, Creating a Child Process with Redirected Input and Output[^] If you don't get any redirected output from the sample above... then your third-party console app might be writing to the STD_ERROR_HANDLE rather than the STD_OUTPUT_HANDLE.

You only told us about the scope of input values, and that these values are gathered in batches and processed (filtering out duplicates) before sending out. You didn't tell us if anything of this is time-critical, or you're working with restricted amounts of memory - should we try to optimize for either? Also, is it more important for the receiver to receive the data in a timely manner, requiring on-the-fly processing so you can send out the batch right after the end of the cycle - or can you afford to delay the processing until after receiving the last input of the cycle, before sending it out? The answer to these questions will influence what algorithm to use, and the algorithm will influence what data structures to use. GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them.

I have no way of checking whether that article is correct or not, I suggest you try some feedback to Microsoft.

You could use a flag in your WindowProc, which starts as false and gets set to true if you receive a touch input. At the end of the routine if the flag is still false then set your value to zero.

Have a look at this page "Modulus without Division, a tutorial"[^]. Veni, vidi, vici.

Sorry, my original message was incorrect (the MSDN description lacks clarity). This should capture all messages, not just those directed to your application.

Thanks for your valuable suggestion. I am trying all this, I will update you once I will collect the result.

With Windows 7 SP1 or installed KB983246, the ADO DLL has been changed. See http://support.microsoft.com/kb/2517589/en-us[^]. Solution 1 (install updated libraries) See http://blogs.msdn.com/b/psssql/archive/2011/10/03/yes-we-made-a-mistake-and-are-finally-going-to-fix-it.aspx[^] and http://support.microsoft.com/kb/2640696[^] to download new libraries. Solution 2 (excluding and renaming changed UUIDs) See Your ADO is broken[^]. Use this only when your developing machine uses Windows 7 SP1.

no, i hate QT

Personally, I'd go with the Arduino platform. You can buy an Arduino Pro Mini (clone) for about $4 on flea-bay, which you could either couple with a 16x2 character display complete with buttons, or with a 128x160 16-bit graphics display and some extra buttons. In either case, you should be able to build the device for under $15. Arduino gives you the advantage of writing in C/C++. The Nokia 101 looks like programming would be something more of a task.

Please, I have order problem. when I do this: CRecordset recordset(&database); CString temp, query; query.Format(L"SELECT number FROM personne WHERE numPiece = '%s'", numPiecPer); recordset.Open(CRecordset::snapshot, query, CRecordset::appendOnly); while (!recordset.IsEOF()) { recordset.GetFieldValue((short)0, temp); messageBox(temp, 0, 0); recordset.MoveNext(); } It don't work. :(

Thanks for reply. I did not specify which issue I need help with. Sorry. As I said, I'll figure out the update "problem". I feel the property sheet dialog should do the update just fine. But I am just curious why the difference between GraphEdit using "off the shelf" filters both Ezrgb24 and Color Conversion Filter. I did some search and found some discussions to the effect that GraphEdit does some extra work when displaying property sheet. I think I found my problem, but it will take some undooing to fix it. For safety reasons I did make copies of both filters and compiled them. For so far unknown reason the options tab page in property sheet is gone, only the pins pages are there. I assume this page code is external to the filter code. That is why it works when filters are added manually in GraphEdit - it uses the original source.

I mostly use hex flags, I think that's the most common method. It's probably because it's a lot clearer which bits are actually set (for that same reason, I don't think I've ever seen decimal used for flags since the conversion isn't as neat). Empty flags have a definition if they have a meaning (i.e. not necessary but could be labeled for clarity).

Thanks, CreateFontIndrect work for WinCE also. Now it solved. seems when the IDE pop up a message window, ask me if I　hope to change the character set, I clicked no.

iFileCountInFolder is always fixed, since the files in a folder are fixed , means no files are added at run time. I did not understand why the Free statement is failing.

I donot know your C program. Please talk me you realize the function. I come from China.My English is not good.I hope you can understand my replay.
