Re: Detect code page/encoding of a text... Paul Selormey15-Jun-02 1:17 Paul Selormey 15-Jun-02 1:17  How about if I have the text file? Best regards, Paul.

Mike Nordell16-Jun-02 6:00 Mike Nordell 16-Jun-02 6:00  You still only have the characters (the "text"). You can't possibly know anything about what language and code-page was used to produce that file without some kind of meta content, wether in the text itself or as an alternate stream for the file or whatever). Re: Detect code page/encoding of a text... Paul Selormey16-Jun-02 14:05 Paul Selormey 16-Jun-02 14:05  The "Advanced Save As..." dialog in the VS.NET seems to indicate the correct codepage. What is the magic here? Best regards, Paul. Paul Selormey, Bsc (Elect Eng), MSc (Mobile Communication) is currently Windows open source developer in Japan. Re: Detect code page/encoding of a text... Mike Nordell17-Jun-02 17:54 Mike Nordell 17-Jun-02 17:54  For a plain text file? I haven't got a clue. Named NTFS streams? Re: Detect code page/encoding of a text... Michael Dunn15-Jun-02 6:07 Michael Dunn 15-Jun-02 6:07  A code page is simply a mapping of a byte value to a glyph. Only a person can tell if text is being mapped using the right codepage - they have to look at the output and decide if it looks correct. To the computer it's all just bytes. --Mike-- Just released - RightClick-Encrypt - Adds fast & easy file encryption to Explorer Like the Google toolbar?

How to use an ActiveX control in ATL LiamLee14-Jun-02 20:57 LiamLee 14-Jun-02 20:57  I want to integrate MSCOMM.ocx into another ATL component. First I create a composite control in the ATL component. Second I insert the MSCOMM.ocx into the component. It creates two files mscomm.cpp and mscomm.h. Then I declare a variable of CMSCOmm class. I don't know how to bind the variable and the control ID( Like the MFC: DDX_Control ). So I attach the hwnd of the control to the variable. But when I run, it will throw an assert on the line: ASSERT( m_pCtrlSite != NULL ); Who can help me solve this problem? Heap mangament in a multithreaded windows application sailesh14-Jun-02 20:32 sailesh 14-Jun-02 20:32  Hi everybody! I have a typical problem here. My application is a multithreaded one. In one of the cases, there are multiple threads which will be using a common buffer which is a member variable of a particular class. This buffer is also allocated memory by one of these threads and to be accessed by the other threads. I am getting a dbg_heap error as debug assertion. How do i go about solving this problem. Please help me out as this is very urgent. Thanx in advance. regards, sailesh Re: Heap mangament in a multithreaded windows application Joaquín M López Muñoz15-Jun-02 2:00 Joaquín M López Muñoz 15-Jun-02 2:00  If all of your threads are launched within the same program (i.e. there are no DLLs or external libs involved) then your problem most likely has nothing to do with multithreading issues, but rather chances are you're somehow corrupting the buffer (by writing out of its bounds, for instance.)

It's just a simple insert, and doing it as a normal insert crashes with 'invalid character', but writing the same query to disk and passing it to Oracle by hand works fine.

I am sure about one thing ';' ain't going to work. It may be happening that while constructing the query something may have comeup like quotes which oracle doesnot like. This is what I was hinting yesterday when I was telling you about unfriendly oracle error messages. "Invalid character" doesnot mean anything atleast if position is indiacted I am willing to give them a 'C'. Anyway good luck!

It took me 3 days to track this problem. Re: Oracle/ADO HELL Michael P Butler14-Jun-02 22:46 Michael P Butler 14-Jun-02 22:46  Can you post the ADO code.

Every thing I have tried, if streamed to a file, works right away in SQL+. The stored procedure hangs indefinately, and it looks like this: (QFileID IN tblAttachmentVersions.qfileid%TYPE, DataID IN tblAttachmentVersions.RevisionCount%TYPE, Filename IN tblAttachmentVersions.filename%TYPE, MimeType IN tblAttachmentVersions.mimetype%TYPE) IS BEGIN INSERT INTO tblAttachmentVersions (QFileid, RevisionCount, binaryData, filename, mimetype) VALUES (QFileID , DataID , empty_blob(), Filename , MimeType); END; Thanks for the help.

I have been trying to do this for some time now with no success. Re: Attaching menus to command buttons Paul M Watt14-Jun-02 16:38 Paul M Watt 14-Jun-02 16:38  When the button is clicked, use the TrackPopupMenu API to make the menu that you want to appear. This is the same function that you use if you want to create a right-click or context menu.

ClassName for a Dialog App Bradley Manske14-Jun-02 15:04 Bradley Manske 14-Jun-02 15:04  I've written a Win32 Dialog App that calls CreateDialog instead of CreateWindow. When it starts up I wanted to use FindWindow along with a class name to see if the app was already running. To do this I need a unique ClassName, but the class is created by the call to CreateDialog. I have tried using the CLASS statement in the resource file, but then the call to CreateDialog fails. The API documentation for DefDialogProc hints that RegisterClass can be used to set the ClassName for a Dialog. It further states that GetClassName can be used to get the WNDCLASS for a dialog, then the name can be changed and a new class registered. I think this is standard Win32 stuff, but in case it matters, I'm working with WinCE. Has anyone ever done this? Nothing works as expected for me. Is a different approach called for? Suggestions? Comments? Brad Manske Re: ClassName for a Dialog App Paul M Watt14-Jun-02 16:55 Paul M Watt 14-Jun-02 16:55  A better way to limit multiple instances of the app is to create a named mutex. Only one app will be able to do this at a time. If the mutex already exists then you can assume that your program is alreay running, the same way you would if the window was already found. There are some gotchas to both methods so look at this article. Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life!
