• Kiran Pillai Editing Array of string values from CSV file

  I'm new at this so please bear with me. I have a CSV file that contains about 500 rows and 50 columns. I need to keep all the rows but only keep columns 1,2,3,4,6,7. I've opened the CSV and stored each row as a single element in a one-dimensional array. What I need to do now is search through those array elements and remove everything except column 1,2,3,4,6,7. Am I approaching this problem correctly If so, how do I proceed I'm stuck. How can I read until the 7th column What would I need to add to the code I also need to omit the 5th column. Thanks for the help. When I try to print the contents of the array, I get 500 values of System.Collections.Generic.List'1[System.S ...Show All

• Sincas bug in wingdi.h ?

  Hello, could someone verify this is bug : #define GetGValue(rgb) (LOBYTE(((WORD)(rgb)) >> 8)) Atleast for me it throws runtime-check-error when used. """ Run-Time Check Failure #1 - A cast to a smaller data type has caused a loss of data. If this was intentional, you should mask the source of the cast with the appropriate bitmask. For example: char c = (i & 0xFF); Changing the code in this way will not affect the quality of the resulting optimized code. """ Change to #define C_GetGValue(rgb) (LOBYTE(((WORD)(rgb&0xFFFF)) >> 8)) helps, so it seems like a small bug in headers to me. I wouldn't like to spam the Microsoft Connect with this th ough...

• Njofra Find in Files and View->Find Results 1 window no longer work

  Greetings, I have come across a bug in vs2005. My Find in File no longer works. Every time I press it Dev Studio looses focus but the Find in Files dialog does not come up. Nor can I bring up the FindResults1 window, However the Find Results 2 does still work. Another thread has posted a "Fix" is to try pressing Ctrl + ScrLk and/or Ctrl + Brea. One even suggests trying this during a compile, I have tried to no avail. It amazing how much you use it without thining and how much you miss it when its gone. Crippled, I tried a full unistall + reinstall and it still does not work. Perhaps this is a registry bug entry Help, I have to get this working, I'm one step away from having to reinstall windows!!!

• niroshanonline RLE Compression????

  hi everyone, I am doing project that requires me to do a compression of a bimap file in c++. I came after "RLE Compression" after browsing through some sites. Coz i am quite new to c++, i have no idea how to do a RLE compression. Do anyone have a site or a sample to share about RLE Compression Thankz you so much. Regards Natoia The easiest way to compress a bitmap is to save it in the GIF or JPEG format. Of all the standard bitmap formats around, only TIFF uses RLE compression. BMP is rumored to support RLE but I've never seen it... If this is a homework assignment and you need to come up with a way to compress a bitmap, RLE compression is the way to go. It is a simple co ...Show All

• Wint Creating Windows Shortcuts (Shell Links or .lnk files)

  I am having issues figuring this out. In Visual C++ 2005, I am trying to create a shortcut. At this point I don't care what the shortcut is for or where it will go. I've seen references to the Windows Scripting Host Object and the IShellLink interface. Neither of which can I figure out how to use. When I referenced the WSH, I was getting errors about undefined identifiers, I guess because I don't have any kind of header file to use. Any help would be appreciated. Thanks. That's a very good article, but I don't think it has much to do with .LNK files. Am I missing something LNK files look to be a very fundamental part of the Win32 shell -- not something that's added on as a component. There it is ...Show All

• Ofer Kalisky C++/CLI ICE while passing a member function pointer to template argument

  The original code that caused ICE was different, but I narrowed it down to: #include "stdafx.h" using namespace System; struct Dummy { void bar() {} }; template < void (Dummy::*pmem)()> void foo() { void (Dummy::*memfunc)() = pmem; } int main(array<System::String ^> ^args) { foo<&Dummy::bar>(); return 0 ; } _Winnie C++ Colorizer The ICE occurs at line 14.

• MF Recruit Trace

  What is the trace I found a class and a tool... but what for Is it a particular log file How can I use it That tool is useful to display tracing info generated by an MFC program with the TRACE macro . The Trace class is a managed .NET class, useful to generate tracing info in a C++/CLI program. Check the docs on how to use them... It's installed when you install the VS 2005 IDE. If I don't wrong there is something like it in VC++ 6 also. But I didn't understand what it's in general. That still doesn't narrow it down.

• Sean Connolly My app get's hung up some times and is not responding

  I am developing this simple arithmetic program and this is my first windows application ever, so I am not so sure at how to program this. In my app the user can set the lower limit and upper limit for the calculations numbers that are about to come up in a test the user want’s to do. You se the upper and lower limit as variables in the code below. The code below generates calculations for addition, subtraction and multiplication. So let us suppose that the user sets the limits to lower = 1 and upper = 100, that will give us 100 x 100 = 10 000 calculations! When I test this on my own computer it takes a while to generate all calculations, and if I change upper limit = 200 the program stops I push (ctrl+alt+del) and it says that the applica ...Show All
