Hi,
I can't able to display image as per your suggestion. Actually , the binary data stored into jpg file and then opening image file using any one of the image editor. But the file is not loaded into that tools even if that jpg have contents.

Hi everyone,
If I have a lot of images does this way correct or no?
I use of a listctrl with imagelist and use of Timer(WM_TIMER) for read images of hard and insert to listctrl and since images are jpg I use of cimage class for read their and convert to hbitmap for insert to listctrl.
Is this correct or no if no can you suggest me a way.
Thanks

What is the purpose of the timer ? What do you want to achieve ?

I have a lot of images and I think its not suitable that I use of while or For so I think its better that I read this images on timer (WM_TIMER) Is it good

Hi,
In my VC applications, i need to use static members and methods for a callback function. The dialog was modal. Now i need to change the dialog as modeless. Does the static members would affect the display of results that are from the callback functions?
The result from the callbacks are inserted in the list control.
The problem am facing is , after converting the dialog to modeless, if i open the dialog (more than 1), the result from the callback is displayed in one only dialog.
Please clarify.
Thanks

Can you show some code for your explanation ?
|
|
|

All the dialog instances are going to share the static variables.
If the list control is static then you have a problem - each instance of the dialog needs its
own list control object because each will have its own HWND.
If the callback is setup from in the dialog class, then is there a way you can have the callback
called with some parameter to differentiate between the different dialog instances (like a pointer
to a dialog object)?

List control is not static.

Hi,
I want my application will be displayed in Multiple language without creating
dialogs each one for each language.
How can i do it?

Refer localization [^] section of this site.
You will get good idea , how to acheive this.

Adding to the above reply, make sure your application is unicode aware. Store literal strings to be displayed in a string table instead of hard-coding. Then load them accordingly.

My Application is unicode aware. And also i loaded strings from string table. Now i put the menu which is for displaying different languages.
Now what i want is when i click chinese ,the GUI will be displayed in chinese.. how can i do it ?

I serialized data to a file. Data file consists of many lines, so each has it's carriage return at the end. The problem is, the reader cannot pickup the carriage return. My observation is, when I open the file with Notepad++ or Wordpad, you can visually see the carriage return. When open with notepad (and my application's reader class), the carriage return isn't picked up.
Here's the code extract ...
1. Writing to data file
<br />
CFile oFile;<br />
oFile.Open("...", CFile::modeCreate|CFile::modeWrite|CFile::shareDenyWrite);<br />
<br />
for(int nIndex=0; nIndex<nSize; nIndex++) {<br />
strLine = oLines.GetAt(nIndex);<br />
<br />
strLine += L"\n";<br />
iLen = strLine.GetLength();<br />
pMultiByteStr = new char[iLen]; <br />
WideCharToMultiByte(CP_ACP, 0, (LPCWSTR) strLine.GetBuffer(iLen), -1, pMultiByteStr, iLen, "", &bUsedDefaultChar);<br />
oFile.Write(pMultiByteStr, iLen);<br />
}
2. Reading from data file [It simply read one line and exited]
<br />
int CSomeClass::ReadThisFile{<br />
int iCount = 0;<br />
CString sLine;<br />
CStdioFile oFile;<br />
<br />
try<br />
{<br />
if (!OpenFile("..."))<br />
return 0;<br />
<br />
if (m_bHeaderRow)<br />
oFile.ReadString(sLine);<br />
<br />
while (oFile.ReadString(sLine))<br />
{<br />
if (sLine.GetLength() > 0)<br />
iCount++;<br />
} <br />
oFile.Close();<br />
}<br />
catch (...)<br />
{<br />
...<br />
}<br />
<br />
return iCount;<br />
}<br />
Any clue? Thanks

What if you try a carriage-return/linefeed pair?
strLine += L"\r\n";
