Hello! if you only check the string of the filename,you can check if the string have the list of "./?;'". if you check whether the file is existent, you can use code as follow in VC6.0 : BOOL CheckIfFileExists (LPCTSTR szFileName) { ASSERT( szFileName != NULL ); if( _tcslen(szFileName) == 0 ) return FALSE; DWORD dwAttr = GetFileAttributes(szFileName); if( dwAttr == 0xFFFFFFFF ) return FALSE; return (dwAttr & FILE_ATTRIBUTE_DIRECTORY) == 0; } dupengfei

Your program can't locate library named "fltk.lib" please add the correct directory of fltk.lib into setting panel in project menu. position: choose "link" category : input object/library modules : "your path of fltk.lib" dupengfei

hi Maybe your computer donot support Big5 code. CString is a good idea to process string. if you can't use it. I suggest that: to vc, char also is integer type, so you can do it as follow: static DWORD szChar[]={"你好嘛？"} hope a little help for you! dupengfei

hi! When you saved the temp file , I think you didnot make the properly bitmap header which is a struct "BITMAPINFO". so it displayed blank picture. good luck dupengfei

please include"stdafx.h" in source file and header file, or turn using precompilerd header off in program setting. if you turn on using precompiled header, vc will compile the source code beginning at stdafx.h hope this helps to you. dupengfei

hi! where is onsearch() called in? Maybe you have called this function in other procedure actived by EN_SETFOCUS message. dupengfei

I think the ide havenot create browse file for workspace. rebuild it,and cover cursor on the mothed, press F12,you can reach to where it definited. dupengfei

I suggest that : first way: maybe you can use IStorage and IStream; before user change the object, you create IStorage object and save user's object data to Storage. if user undo his change, load this object. secondly: use clipboard, you can create the different clip tags but the tags have the same letter such as "'object1', 'object2','object3'...." if user undo object3, you can load object2. certainly, the memory is limmitted. so can set fixed num for operatoring. hope helpful for you. good luck dupengfei

Ocracle give you powerful function. it can manage the largest data. ADO is Com compenment and can place the odbc. dupengfei

CMemFile fMem; LPBYTE lpByte = fMem.Detach(); after create the memory file , you can use this function "Detch" to get the pointer to file. then operator it with pointer freely. dupengfei

CMemFile is the CFile-derived class But supports memory files . if you want particular content, press "CMemFile" in the index cote of MSDN. the article is detailed in msdn. dupengfei

Maybe CMemFile help you. pengfeidu

for storing the object,I often use CFile class to write into disk, or use IStorage and IStream. dupengfei

Joe Woodbury have detailed it. the same you can include"stdafx.h" to solve it . dupengfei

please give the internet address out dupengfei

Maybe you didnot register on others' computer dupengfei

is the class view empty? yeah,when I link to the sourcesaft control, that is like you. dupengfei
