I got a ownerdrawn clistctrl that I have a bk image in.
How do I make the selected item background color about 50% transparent (I want to blend it with the bkimage)?
|
|
|
|
|
In the CListCtrl::DrawItem(LPDRAWITEMSTRUCT) function, you can manage the CDC object for fill each item to transparent.
I also need this implementation (with 100% transparent), and if you get please tell me how make it.

What the program actually does is that it searches an input file containing special characters contained in some words(i.e Ô , * and #352; ) .After finding such words it replaces those characters with this (i.e \o^ , \e^ and \sh respectively).I hope you will have the picture now.
SPECIFICATION
Deal with input or check whether input has the following special characters, i.e. read a file of text containing a list of words and check for the occurrence of these characters:
Ô or ô * as used in the word "pôô"
* or * - as used in the word "r*ma"
#352; or #353; - as used in the word "le#353;a#353;a"
If a word has any of these character replace each character by the
following characters respectively:
ô with \o^
* with \e^
#353; with \sh
I would appreciate it if you could could have a short program to sort
this issue out.
Let me say that it should be like this:
input -> words.doc
pôô r*ma le#353;a#353;a aôwô b*thô
output -> c:\output.txt
p\o^\o^ r\e^ma le\sh;a\sh;a a\o^w\o^ b\e^th\o^
Yes the text file is ASCII format(that "#352;" represent an S with a cap on top).It is Northern Sotho language(South African language)

The simple way is to use a lookup table e.g. char lookup[256];
each element will contain the character that is to be displayed for relevent ASCII value e.g lookup[235] = '?'; The majority will probably be the "standard" ASCII values.
So read in a buffer and use the look up table to convert each character, to a new or the same buffer;
This solution is only really valid if there are a lot of mappings that change, otherwise it can be slow. If there are only a few use a simple case statement for the mapped characters.
Of couse you could look at the ASSCII code chart and see if a simple mask would do the job, e.g. converting lower to upper case.

Can't think of an application to do this off the top of my head.
However, if what you are looking for is API capable of doing exactly this you could start with:
1/ boost::regex[^]
2/ System.Text.RegularExpressions in the .NET framework
The benefit of using boost::regex is that you get a little more flexibility.
The benefit of using the .NET framework is you can code it in C# and it'll be about 1/4 the size.

How can i convert _int64 to string? Normally whenever i need to convert numbers to string i use the following code:
**************************************
int num = 123;
std::string strNum;
std::strstream strm;
strm << num << std::ends;
strNum = strm.str();
***************************************
This always works fine for me if the data type of a number is 'int' or 'float'. Today for the first time i need to convert an '_int64' number to string. I am using the code i described above but i get the following error:
ServerMain.cpp(79) : error C2593: 'operator <<' is ambiguous
Can anyone tell me the cause of problem and its solution

_int64 is a compiler specific data type. Therefor it is not supported by the STL which is by design compiler independant (at least it's supposed to).
You can use the printf() family of functions, they support _int64 via the prefix I64 (but only on MSVC). So this should work:
sprintf(my_char_buffer, "%I64i", my_int64_num);

However true, it's also irellevant. The STL (which technically has no merit any more, since Mars 1998) didn't even touch the matter.
If we on the other hand talk about the C++ library: vendors are free to extend the library with e.g. compiler specific data types, and both Dinkum (MSVC7 and __int64, though with the name _LONGLONG) and the GNU C++ lib do provide these insertion operators for 64-bit integers (VC6 is another matter, but it's very easy to augment the lib to handle 64-bit integers).
In fact I expect (especially for proprietary) compiler/lib combos to provide operators for all of the compilers POD types. I almost wrote "native types", but stopped myself knowing that any IA32 64-bit integer support must be emulated.

Hi CPians !
My MFC Dialog app needs to be runned single under NT/XP. To that end I use PJNaughter's single instance which works very fine. I have associated some config files to my app, so that when the user double clicks on them, my app is opened. So far so good.
If my app is already running when the user double clicks on a cfg file, I'd like to send a message from the second instance to the first with the name of the file to open in it, so that i can open the config file in the first, and kill the second.
BUT I can't get this to work.
I use a registered message, which is arriving properly and handled properly with ON_REGISTER_MESSAGE, but I can't retrieve the sent string. :
App2 (which is to be terminated) :
CString Filename="C:\\Myfile.cfg";
::SendMessage(WM_USER_2NDOPEN,(WPARAM)(Filename.operator LPCTSTR()),0);
App1 (which should process the message :
LPCTSTR buff;
buff=(LPCTSTR)wParam;
won't work. I have tried about everything, using LPSTR, LPCSTR, LPTSTR, LPCTSTR (so Unicode and not Unicode), even a CString, or a char[1024] or a char * (I know some of these solutions are redundant) passing each time the address of the string to the first app, and tried every possible configuration of typecasts in the receiving function, but I can't seem to retrieve the sent string (most time, when the casts make sense, I have "IIIIIIIIIIIIIIIIIIIIIIIIIIIIII..." in the buff). And the Send instead of Post makes sure the string does not get destroyed before I read it from memory.
The weirdest thing is that if I replace the CString, or the LPCTSTR or what in the App2 with :
::SendMessage(WM_USER_2NDOPEN,(WPARAM)"RaGE",0);
Then I can retrieve the string without any problem, whatever the format and typecast I use in the receiving function in App1. 
My temporary solution is that I save the filename in a text file on the disk in C:\\Temp in App2, send the message and retrieve the name by reading it frim the file in App1. But I think this solution really sucks. 
I'd like to do it the right way, and I'm sure it _is_ possible to send a string using a windows message...
Can you help me ?

Hi,
I need to show different tooltips for different positions in the same window.How to implement this.
|
|
|
|

First of all, check the rect position of tooltips, and make tooltips each and all.
I implemented it once.

I made a printer driver installing program.
Adding printer and adding printer driver work perpectly.
In adding printer, I check that the same printer driver have been already installed with OpenPrinter().
I use a handle from OpenPrinter() to implement DeletePrinter(). I think this is common way.
But DeletePrinter() don't work.
DesiredAccess, member of PRINTER_DEFAULTS that specifies desired access rights for a printerstructure, affect the operation of the SetPrinter and DeletePrinter functions on MSDN.
So I did OpenPrinter() with setting DesiredAccess, but this cause an error, Unhandled exception in Install.exe (WINSPOOL.DRV):0xC0000005:Access violation.
Please advise me after check my source following.
////////////////////////////////////////////////////////////////////////////////////////////
PRINTER_DEFAULTS stPD;
HANDLE hPrt;
stPD.DesiredAccess = PRINTER_ALL_ACCESS;
if ( OpenPrinter( (char*)(LPCTSTR)sName, &hPrt, (LPPRINTER_DEFAULTS)&stPD) )
{
sTmp = "Already, same driver is installed.\nReplace old driver with new driver?";
if (IDYES != MessageBox(sTmp, sCoName, MB_ICONQUESTION|MB_YESNO))
{
MessageBox("Driver install is canceled.");
return;
}
if (!DeletePrinter(hPrt))
{
sTmp.Format("Can't delete driver (Error No. %d)", GetLastError());
MessageBox(sTmp);
return;
}
}

I am wondering if the VC compiler uses multiple threads in compiling source code, i.e. will compilation speed scale linearly with number of processors?

when i create a project following the wizard, I may find
the final installation files include all the files i put
into the file group of this project such as my exe file,
my icon file and so on.
Someone told me I can create a single setup.exe file by
using the tool PackageForTheWeb of installshield, but I
still want to know how can i create a project only include
some installshield stardard files (i.e. data1.cab,
licence.txt, setup.exe and so on) just like some other
softwares. I think all my own program files should be in
the data1.cab, shouldn't it?
Thank you.

No-one is going to wade through your code if you don't even say what the error is, but VC6 is one of the worst compilers for C++ standards conformance.

LOL - so the compiler works fine then. If it works with your other compiler and runs, chances are it's inserting a workaround for a function you're calling that is NT only. Or your build settings are creating the problem.
