How to write a plugin for IE CodeToad.Com5-Sep-04 23:39 CodeToad.Com 5-Sep-04 23:39  Can anyone give me a pointer or two on how I go about writing a plugin for Internet Explorer. I can't seem to find anything on it on the web. Re: How to write a plugin for IE User 66586-Sep-04 1:05 User 6658 6-Sep-04 1:05  Search for "Browser Helper Object" or "BHO". You will find some examples here at codeproject.com as well. regards modified 12-Sep-18 21:01pm. Re: How to write a plugin for IE Anonymous6-Sep-04 20:50 Anonymous 6-Sep-04 20:50  Here's a great article to start with (if you're familiar with COM). If you're not, you might want to brush up on COM before tackling a BHO project. You're always free to develop a BHO in raw C++ however, ATL is the preferred method. http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnwebgen/html/bho.asp Does this answer your question? or, did I completely misunderstand your post.

If you are using NT/2K or XP then things get more tricky. Basically, you need a driver to allow direct access to the parallel port (which is not normally allowed). I used one ages ago, which you could give a range of I/O addresses, and you could read or write to them via a DLL. I can't remember what it is called, but Try googling for "parallel port access windows driver". Re: Plss!!!Help!!!! in parallel interfacing in visual c++ CoreyCooper6-Sep-04 14:02 CoreyCooper 6-Sep-04 14:02  I've sucseffuly used a general purpose device drive called "TinyPort". It's good, but it warns you that it is relativly slow, being that it is general purpose, not specific to a device.

Pass "LPT1:" as filename. Arsalan Malik Small problem with MDI, Please help!!!! Azghar Hussain5-Sep-04 22:57 Azghar Hussain 5-Sep-04 22:57  Hi Everybody, I have a small problem with MDI application. Actally I want to customize MDI application in such a way that if some one open menu->File->Open we will get file open dialog box. I want to customize this file open dialog box so that it obeys only .BMP extension file. Please note that I don't want to write my CFileDialog object and handle menu. I just want to customize the default file dialog so that it only obeys .BMP file extension. Thanks in Advance Salman Live and Let live Re: Small problem with MDI, Please help!!!! YunYan6-Sep-04 1:05 YunYan 6-Sep-04 1:05  Hi, You can define the CFileDialog object as following.

I want to convert my "CString" to "LPCWSTR" type.. How can I do this??? Plz help me out .. Thanks Sudhakar Re: Conversion of CString to LPCWSTR Arsalan Malik5-Sep-04 23:03 Arsalan Malik 5-Sep-04 23:03  Use the function mbstowcs. It takes a char pointer, so use GetBuffer function of CString to get char pointer. Alternatively you can use AllocSysString method to BSTR, which can be easily passed as LPCWSTR. Arsalan Malik Re: Conversion of CString to LPCWSTR Archer2826-Sep-04 4:39 Archer282 6-Sep-04 4:39  use the member function GetBuffer() Link to microsoft documentation of CString::GetBuffer example: CString MyString("This is my string"); LPCWSTR MyLPCWSTR = (LPCWSTR) MyString.GetBuffer(MyString.GetLength()); note: the return type of GetBuffer() is LPTSTR Re: Conversion of CString to LPCWSTR Sudhakar Pasupunuri6-Sep-04 19:26 Sudhakar Pasupunuri 6-Sep-04 19:26  Thanks for the info.. It was working perfectly.. Thanks Sudhakar Re: Conversion of CString to LPCWSTR David Crow7-Sep-04 3:13 David Crow 7-Sep-04 3:13  Remember that for every call to GetBuffer(), there must also be a call to ReleaseBuffer(). If you are not going to be editing the internal CString buffer, why ask for a writeable copy? Try this instead: CString MyString("This is my string"); LPCWSTR MyLPCWSTR = (LPCWSTR) ((LPCTSTR) MyString); "When I was born I was so surprised that I didn't talk for a year and a half." - Gracie Allen Function to check if “C:\\myFile.txt” exists anderslundsgard5-Sep-04 22:29 anderslundsgard 5-Sep-04 22:29  I know there is a small function that checks if a file exists but I can’t find it. _____________________________ ...and justice for all APe Re: Function to check if “C:\\myFile.txt” exists BAIJUMAX5-Sep-04 22:42 BAIJUMAX 5-Sep-04 22:42  hi , try this out CFileFind oFileFind; if ( oFileFind.FindFile("C:\\myFile.txt") == 0 ) MessageBox("File Not Found") by baijumax;P Re: Function to check if “C:\\myFile.txt” exists anderslundsgard5-Sep-04 23:24 anderslundsgard 5-Sep-04 23:24  You're the hero of the day _____________________________ ...and justice for all APe Re: Function to check if “C:\\myFile.txt” exists BAIJUMAX6-Sep-04 2:43 BAIJUMAX 6-Sep-04 2:43  hi apeman, thanks 4 u r comment.why don't u wish me, hero of future computing. by baijumax;) Re: Function to check if “C:\\myFile.txt” exists Arsalan Malik5-Sep-04 22:54 Arsalan Malik 5-Sep-04 22:54  You can use FindFirstFile and FindNextFile functions in API.
