Looping through a string - C / C++ / MFC Discussion Boards

Insert a Timer function in which the bar gets updated. 100ms is a nice value.:->

Greetings from Germany

AFAIK yes, it is possible, but how accurate it is... depends on code.

Can you show some related lines?

Greetings.

You can create a function in the modeless dialog's class that updates the progress bar's state. Call that function at various points in your process.

Do you have code in place to do the updating?

hi all,

Can anybody help me in converting EXIF format to 24 bit BMP format?,

I got the following details When i checked about the format of the jpg file

1. JPEG FOrmat : EXIF
2. EXIF version : 0220
3. Encoding used : Baseline

kkr

Will this[^] helpful ?

Regards,
Paresh.

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.

What is this snippet of code supposed to do?

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

KIRAN PINJARLA

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.

Thank you so much.

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

fatal error C1190: managed targeted code requires a '/clr' option

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.

DoEvents: Generating unexpected recursion since 1991

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
bankey

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.

don't repost!!!

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