If you don't want to do the JPEG decompression yourself, you could use
GDI+.
For example, using the shared Visual C++ class CImage (which uses GDI+ for loading/saving)...
CImage img;
img.Load(_T("C:\\Path\\MyEXIFfile.jpg"));
img.Save(_T("C:\\Path\\MyEXIFfile.bmp"), ImageFormatBMP);

Hi,
Im trying to loop through a string to get all layout of words in a forward manner and then search for patterns elsewhere.
I first created this:
spacePos.push_back(0);
for(int j = 0; j<input.length()+1; j++)
="" {
="" if="" (input[j]="=" char(32)="" ||="" j="=" input.length()){
="" spacepos.push_back(j);
="" }
="" }
basically="" pushes="" integers="" onto="" a="" vector="" of="" ints,="" with="" the="" start="" and="" end="" position,="" also="" where="" any="" spaces="" are.
then="" i="" try="" ot="" loop="" as="" so:
="" for(vector<int="">::iterator ii = spacePos.begin(); ii!=spacePos.end(); ii++)
{
for(vector<int>::iterator ii2 = spacePos.begin(); ii2!=spacePos.end(); ii2++)
{
if (*ii2 == 0 || *ii >= *ii2) continue;
if (input.substr(*ii, *ii2) != "")
{
//other code
}
}
}
so if the input line was "hello i am" it would 'hopefuly' do this>
"hello"
"hello i"
"hello i am"
"i"
"i am"
etc
but the problem is, i'm counting the spaces in the first for loop and storing them and after the first iterator of the for loop for ii, it's going out of sync and the longer the string the more this affect occurs:
"hello"
"hello i"
"hello i am"
" i"
" i am"
i tried trimming but it just causes so many problems with long strings so i really want to sort this out in the first for loop where i obtain all the space positions.
Does anyone have any ideas? or maybe even a better way to do what i want?
Cheers

The first thing to verify is that spacePos contains exactly what you think it should. If it doesn't, then the other two for() loops are irrelevant.

i am using vc2005 and the code is compiled in unicode mode. How to disable it?

To disable unicode support and use multi-byte support instead, go to your project properties (right-click on your project and select properties under Solution Explorer), then go to "Configuration Properties" in the treeview on the left, select "General", and change "Character Set" from "Use Unicode" to "Use Multi-byte character set" from the property list on the right.

I need one more help. I am debugging some pre written code. I found
#using<somex.dll> in that. while i am compiling its giving an error

What does it mean.

Choose the item yourproject Properties of the menu Project
(yourproject stands for the name of the current active project),
then select Configuration Properties->General in the newly appeared window.
Finally change the Character Set property.

Don't. Windows NT APIs are entirely Unicode-native - if you run an ANSI application on Windows NT-based operating systems (NT 4.0, Windows 2000, XP, Server 2003, Vista and later) all your strings get converted back to Unicode before being processed, and if asking for string values the results will have to be converted back to ANSI from Unicode.
Also, you will find it much more difficult to localize your application. Some scripts are Unicode-only, there is no equivalent ANSI code page.
Right now you should only think about compiling an ANSI application if running on Windows 98 is a requirement - and these OS usage share statistics[^] are showing less than 1% usage, barely more than Linux - and if that is a requirement, you should consider looking into the Microsoft Layer for Unicode[^], which allows programs compiled for Unicode to run on Win9X.

Hello All,
i am working on application using directx with VC++. when i change resolution setting than my graphics gets distorted.
i want to set fix aspect ratio for my application.
if any body have idea about that please share with me.
thanks

A way would be to find out a coeficient to relate the needed size with the actual resolution. Then get the desktop apearance and apply the needed multiplier to your graphic.

In my project I need to write text to file. For that I need to display the Save dialog and there user should be able to create folder and enter file name to save the file in that location. How can I do?
Actually I need to display the Save dialog on click to One command button.
|
|
|
|
|
When you show save dialog CFileDialog m(0); m.DoModal(); you can check return value of Domodal and then use of GetFileName();,user can make folder in this dialog.

In addition to Hamid's answer, the Win32 API way is to use GetSaveFileName

Hello,
I am having problem with SQLBindParameter().
I have done the following
UCHAR query3[30] = "{call tryproc1(?)}";
int UI = 1;
SDWORD ind2=SQL_NTS;
retcode = SQLBindParameter(hstmt1,
1,SQL_PARAM_INPUT,
SQL_C_SHORT,SQL_NUMERIC,
1,0,&UI,0,&ind2);
retcode = SQLExecDirect(hstmt1,query3,SQL_NTS);
In the above query3 string if I replace ? with 1 then the query is executed and the procedure but the question mark doesn't work.
What must be the problem?
Please help.

The problem is that you are not checking the return value of SQLBindParameter(). When it fails, it makes no sense to then call SQLExecDirect().

I use VS2005.
But the problem is that,when I debug a program to some codes,VS usually tell me that there is no source code.Why? The .h and .cpp files are all included.
Thanks.
GOOD LUCK

Are you debugging this program from within a VS project? If so, then are you sure the code you're trying to look at is available? Like, sometimes the debugger gets into Windows DLL code that don't have anything to do with the code you wrote... If not, then I believe there is a way to import CPP/H files into it, but I don't know how.

In fact,all the functions written by my self.
And if i turn on the VS setting to enable difference with source codes,i could debug into the function.
But I don't know why .
Thanks.
Good weekends.

You should describe the problem more clearly. What is the exact error message (if any) and in which context does it appear ?

Hello, my fellow programmers!
I'm trying to make a (simple) game using the Windows API. There's no animation, and probably won't be any time in the future, so the only time the game screen (which is stored in its own control) needs to be updated is right after user input.
I got this working right by using InvalidateRect(hwnd, NULL, FALSE); after handling WM_KEYDOWN, but this causes a bit of flicker... I thought, "isn't there a vsync() style function?", but then, if the flicker is as noticeable as it is, then that means it's taking too much time to draw the game, which isn't good.
I thought of using dirty rectangles (easy task since the game only consists of 32x32 tiles), but would that completely remove the flicker? Even on slower machines?
Thanks in advance!
