Best Regards Re: About the size of CString David Crow19-May-03 2:14 David Crow 19-May-03 2:14  Can you provide a code snippet of how you are doing this? Re: About the size of CString Drawil19-May-03 2:30 Drawil 19-May-03 2:30  CString query; query=_T("select distinct globalt.Mkname,globalt.Route,globalt.Time,globalt.SI,globalt.NDV,globalt.ANBLO,Avg(globalt.Traff) AS AvgTraffic,Avg( globalt.CCONG) AS AvgCCONG \n" "from globalt \n" "where ((([globalt].[Route]) Like '*SS*' Or ([globalt].[Route]) Like '*I')=False"); Best Regards Re: About the size of CString David Crow19-May-03 2:40 David Crow 19-May-03 2:40  There's only 254 characters there. What's the problem? Re: About the size of CString Drawil19-May-03 20:46 Drawil 19-May-03 20:46  Thank u for ur reply I know every thing appeares normal in my code, but after this step if watch this variable 'query' it equals: "select distinct globalt.Mkname,globalt.Route,globalt.Time,globalt.SI,globalt.NDV,globalt.ANBLO,Avg(globalt.Traff) AS AvgTraffic,Avg( globalt.CCONG) AS AvgCCONG from globalt where ((([globalt].[Route]) Like '*SS*' Or ([globalt].[Route]) Like '*I')=Fal" as u see some char doesnot included "se", even if i add more strings to this variable like query+="any thing" then it doesnt appeare. so this is my problem!!!! Best Regards Re: About the size of CString Drawil19-May-03 23:16 Drawil 19-May-03 23:16  hi again yes that is right there is no problem with CString. the problem was in the Watch window which could not show all char in CString. Best Regards Re: About the size of CString Martyn Pearson19-May-03 2:16 Martyn Pearson 19-May-03 2:16  The MFC CString will accommodate strings far longer than 256 characters. It is more likely that there is something wrong with the code that is populating the CString. Post the code if you still have problems!

VC# dll in a VC++ 6.0 MDI NHM19-May-03 1:31 NHM 19-May-03 1:31  Hi, i have a form in a VC# dll. I'm calling it inside a VC++ 6.0 MDI app. when i create an instance of the VC# dll i set the parent window (the form container) it opens... ok... nothing's wrong.. but the form can overlap the toolbar and the status bar... how can i avoid this?

Tomas Wilhelmsson19-May-03 1:16 Tomas Wilhelmsson 19-May-03 1:16  Ok i got a problem with my object loading, i have it in text files and it loads em 1 by one ... so they get a number 0 1 2 etc. But i want to be able to do GetObj("name"); insted so i just can add a name for the objects in a file and get em that way ... So i wounder, is there any way to get this lookup about as fast as the one with numbers?... i need speed and there might be ALOT of object switching It also has to have the ability to remove and add into the object list under runtime, thats why a name lookup insted of number would be alot better Load("Objectlist.txt"); GetObject(1); // This is the problem, if i load more/change the file it will not be in its right place when used in the program. Load("Objectlist.txt"); GetObject("Wall"); // But as far as i know this is alot slower then using numbers in an vector or something like that Ohh well, hope you understand what i mean and if anyone knows about the speed please tell me how much difrence it would be Re: Getting by name. valikac19-May-03 5:53 valikac 19-May-03 5:53  In theory, yes, given that object names are sorted in the text file. Kuphryn Re: Getting by name. Tomas Wilhelmsson19-May-03 6:04 Tomas Wilhelmsson 19-May-03 6:04  Yes,but then its about the speeds, how much slower would it be to use names to look up the objects then numbers? Re: Getting by name. valikac19-May-03 11:18 valikac 19-May-03 11:18  How long is the filename? Count bytes. Kuphryn Re: Getting by name. Tomas Wilhelmsson19-May-03 21:48 Tomas Wilhelmsson 19-May-03 21:48  The name in the string should be about 10 - 20 bytes... Re: Getting by name. Tomas Wilhelmsson19-May-03 23:06 Tomas Wilhelmsson 19-May-03 23:06  Adding 160 elements Add: 0 Millisecs Starting iteration: 2000000 times. GetByName: 58895 Millisecs GetByPos: 4457 Millisecs This is timings with about 25 char std::strings ... i havent optimized it much. And using a std::vector ... damn thats alot of time! .. its timed using GetTickCount() just for the record And btw, the time did not change if i changed the string to 1 char from 25. The string comparation is only if(*it != Name) so far... Re: Getting by name. Niklas L20-May-03 2:50 Niklas L 20-May-03 2:50  How about writing an index file? Hide physical Disk rohit.dhamija19-May-03 1:08 rohit.dhamija 19-May-03 1:08  Dear ALL, I am working a program to block a physical disk (removable disk, eg c: )so that it should be inaccessible from user mode. For hiding the disk I modified Registry settings: 1) HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NODRIVES which is a 32-bit word (DWORD). ======== if i hide c: by changing above settings , the drive is hidden but i can still access it from address bar or command prompt. Is there any way to block the drive completely ?? Waiting for a positive response. Rohit --------Complete solution for hiding drive------ change the registry value HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies \Explorer\NODRIVES which is a 32-bit word (DWORD). The lower 26 bits of the 32-bit word correspond to drive letters A through Z. Drives are visible when set to 0 and hidden when set to 1. Drive A is represented by the rightmost position of the bitmask when viewed in binary mode. e.g. A bitmask of 00000000000000000000010101(0x7h) The bitmask above hides local drives A, C, and E --------------------------------------- Re: Hide physical Disk svsrikanth20-May-03 2:16 svsrikanth 20-May-03 2:16  hai rohit even i am facing the same problem ,we can still acess the drives from the command prompt. try seeing "Browser Helper Objects: The Browser the Way You Want It" in MSDN this may help u can u share the solution with me once u grt it thx. qrious Http connection timeout Jump_Around19-May-03 1:06 Jump_Around 19-May-03 1:06  Hi I want to send data using POST method.

Now, I need to pass a C++ class pointer to VB that they should be able to use or pass to another C++ dll. Is it possible that I can pass the class pointer as a long value and they can cast it later or something. I am really confused about this and some suggestion or even a small code snippet would be greatly appreciated. Best regards, Pankaj P.S: it is not an ATL DLL. Without struggle, there is no progress
