LukeV28-Sep-02 17:51 LukeV 28-Sep-02 17:51  Hi, I'm trying to set a value to a new key I created, and I get an ERROR_ACCESS_DENIED error when I use RegSetValueEx. Here's some code: lRes = RegCreateKeyEx( HKEY_CURRENT_USER, LoadStringEx( IDS_REG_FOLDER ), 0, "", REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS , NULL, &hkSub, &dwDisposition); if( RegOpenKeyEx( HKEY_CURRENT_USER, LoadStringEx( IDS_REG_FOLDER ), 0, KEY_QUERY_VALUE, &hKey ) == ERROR_SUCCESS ) { // Store ID lRes = RegSetValueEx( hKey, LoadStringEx( IDS_REG_Q_STOREID ), 0, REG_EXPAND_SZ, (BYTE*)strStoreID.m_str, strStoreID.Length()+1 ); // Entry ID lRes = RegSetValueEx( hKey, LoadStringEx( IDS_REG_Q_ENTRYID ), 0, REG_EXPAND_SZ, (BYTE*)strEntryID.m_str, strEntryID.Length()+1 ); } What am I doing wrong??? Thanks! --------------- Concentrating on Ideas http://www.edovia.com Re: Registry question... Michael Dunn28-Sep-02 19:09 Michael Dunn 28-Sep-02 19:09  Two things: Your RegOpenKeyEx() is redundant. Use the HKEY returned by RegCreateKeyEx(). And never use KEY_ALL_ACCESS. It will fail on NT for non-admin users. Only ask for the access you need. --Mike-- Just released - 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

Daniel Turini28-Sep-02 23:09 Daniel Turini 28-Sep-02 23:09  Yes, it can fail because of policies created by the domain admin. KEY_ALL_ACCESS include WRITE_DAC and WRITE_OWNER and domain admins can be quite sensitive about them. "In an organization, each person rises to the level of his own incompetence."

Mike Nordell28-Sep-02 19:21 Mike Nordell 28-Sep-02 19:21  Try creating a black-and-white bitmap. Select it into some DC. Blit the source DC's bitmap into this bitmap, and then it's up to you to read the bits of that bitmap (hint: GetDIBits). Wasn't there a mountain of examples for writing Windows 3.1 printer drivers, including a complete printer driver devkit? Search MSDN and you'll find. o,thanks a lot but...... whelk28-Sep-02 19:42 whelk 28-Sep-02 19:42  sometimes i can built a printer driver ,this cause the installation of the application is complex.i want to realize it in my application then this is good to customer. ----------------------------- Mr.Whelk ----------------------------- Zhuhai City ,Guangdong ,China Re: o,thanks a lot but...... Mike Nordell28-Sep-02 20:30 Mike Nordell 28-Sep-02 20:30  I'm not 100% sure I understand you, but it seems you are trying to output something on a printer that is not (currently) supported by windows. It also seems you only want to 1) get the bits (in B/W) from the source bitmap, and 2) somehow output them to that printer, bypassing the printer driver. For the latter, I suggest you just CreateFile() or even fopen() "LPT1:". If that's not an option, have a look at the GDI API function Escape(). For the former, I suggest you follow my earlier suggestion. From these two suggestions you should be able to produce the output (since it seems you know what the printer needs). ++luck; Re: o,thanks a lot but...... whelk28-Sep-02 21:19 whelk 28-Sep-02 21:19  yeah,what you say is right! 1:i use the CreateFile() open the LPT1 then send the printer command for example print bitmap 0x14 0x47 sometimes i will generate the send data: 0x81---black pixel 0x80---white pixel 0x80 0x04----continuse 4 white pixels 0x82---line end flag byte 0x84---data end flag byte 0x1c,0x47,0x95,0x00,----------------->command and the length 0x80,0x04,0x81,0x03,0x80,0x0a,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x80,0x05,0x81,0x03,0x80,0x09,0x81,0x01,0x82, 0x84 so send these data on printer by LPT1 ,the printer will print the bitmap 2: now my problem is that i want to built a function: char * GenerateData(CString strPrintText); these function can change the strPrintText to above data format; the argument strPrintText is chinese character the return is the data above the key is that i dont know how to generate the strPrintText to the bitmap in the function ,by the way ,i dont want to display the text,all i want to is to generate the data .then get the bitmap data to generate the data format above. that is all .i hope you can help me.thanks a lot. ----------------------------- Mr.Whelk ----------------------------- Zhuhai City ,Guangdong ,China Re: o,thanks a lot but......

There could have been e.g. web-site delays I didn't think of. Anyway, my answer would still be: the key is that i dont know how to generate the strPrintText to the bitmap in the function ,by the way ,i dont want to display the text,all i want to is to You are able to display it I assume? Then: If you are drawing these glyphs into the output DC, you already know how to draw them, and just have to draw them to another bitmap that you yourself then interpret. If you are not drawing them into the target DC, but want to print them anyway, you have to 1) create a bitmap, 2) blit (blt = copy) the contents of the source bitmap into your created bitmap and then finally 3) interpret the bits. To interpret the bits I can only suggest you read up on "CreateDIBSection" and "GetDibIts". ++luck; Re: o,thanks a lot but...... whelk29-Sep-02 16:07 whelk 29-Sep-02 16:07  sorry i cant do it can you give a example application to realize the function? thanks a lot !! ----------------------------- Mr.Whelk ----------------------------- Zhuhai City ,Guangdong ,China ??Resuming a partial download?? Licensed2Code28-Sep-02 14:23 Licensed2Code 28-Sep-02 14:23  Is this the right algorithm to resume an aborted partially downloaded file from the point it was aborted? 1. Read the number of bytes already download = x bytes 2. Inform the server how much of orginal bytes have been read so remaining bytes = (total file size) - x 3. seek to the point it was aborted in the file using CFile::Seek() and start reading from the server 4. At the client side move the file pointer to last bit of the read byte using CFile::Seek() and make sure it doesn't overwrite the existing file. Am I on the right track guys? And how do I prevent the file from not over written? Have a good one guys. "My ass on fire and my brain's on smoke" Re: ??Resuming a partial download??

No. But you're close. Note that without telling explicitly what file transfer protocol you are using you can't get precise answers. If you are using FTP; Instead of asking, do your own research (also know as "Please do your own googling"). Have a look at e.g. FileZilla that does this (and more).

This includes many examples, but they all seem to be using include files and working with messageboes just like in C, in fact i dont really see why i should use Asm instead of C. I mean, where is the code behind, for example CreateWindow(), either in C or in Asm, how is it done? down to the very basics... If anyone knows a good tutorial on this or anything it would be greatly appreciated.

Bad news, fellow, CreateWindow is made in C. Only the innermost kernel features are made in ASM. And this is kept to a bare minimum.

Michael Dunn28-Sep-02 14:34 Michael Dunn 28-Sep-02 14:34  The CFileFind interface is a bit wonky. BOOL bWorking = finder.FindFile ( szFileToFind ); while ( bWorking ) { bWorking = finder.FindNextFile(); Plugins[tag] = finder.GetFileName(); } The return value from FindNextFile() indicates whether you just got the last file in the search, which is contrary to how most classes do it (where the return indicates whether you've gone through all the files). When it returns FALSE, you still have one file left to process. --Mike-- Just released - 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!

I've tried to search through MSDN and studied all(I think) INI-file-related API's, no lucky, i really can't beleive that.
