Why didn't you use similar code in following options and instead of 0/1 use
SW_HIDE/SW_SHOW.
also as sudhir has already suggested you are every time creating dialogs in SelChange notification.
you can move them to InitDialog as suggested by sudhir.

Sandip.

I have cleared some doubts regarding combo box in one of my earlier threads.Had got the solution too.I have a new problem..
I have two dialogs as I told before.there is a combo box in the first dialog.i have a text box in the second dialog.when i click a button, i get the second dialog in which the text box is present.i get the data in the text box in the combo box when i click the ok button .have written code for that.my problem is , i have to see all the data that i enter in the text box in the second dialog into the combo box in first dialog.now what happens is, i can only see the last entered item.i have written it i the OnOK function ,but have commented CDialog::OnOk();
I need to enter details as long as i want and see them all in the first combo box. what to do?
Code in second dialog:
CString i;<br />
fstream f;<br />
f.open("C:\\myfile.txt",ios::app); <br />
printf("\n");<br />
<br />
GetDlgItemText(IDC_EDIT2,str_name);<br />
f.write(str_name.GetBuffer(str_name.GetLength()),str_name.GetLength()); <br />
f<<endl;<br />
<br />
m_combo.AddString(str_name); <br />
<br />
m_edit3.SetWindowText(_T(""));<br />
f.close();
in first dialog:
Add cd;<br />
cd.DoModal();<br />
<br />
m_selcam.AddString(cd.str_name);

projectip wrote: m_combo.AddString(str_name);
Which combo box variable is this.
for adding multiple strings you can create a modeless dialog and use SendMessage(..) to parent dialog
to add strings.
I hope it makes sense.
projectip wrote: Add cd;
cd.DoModal();
and you are able to see only one string because
projectip wrote: m_selcam.AddString(cd.str_name);
this will execute only when DoModal() will return.

m_combo is in the second dialog...thats just for debugging purpose.

Hi,
Why ShellExecuteEx is suggestible to use over CreateProcess,WinExec in Vista. What is the disadvantage if I still continue to use CreateProcess,WinExec in Vista.
Thanks,
Venkat

WinExec function is provided only for compatibility with 16-bit Windows. So even if you are using windows XP, you should not use it.

CreateProcess gives you more control over the spawned process u start, you can spawn it as a different user or different security priveledges and a whole lot more.

Roughly speaking:
-ShellExecute is more developer-friendly.
-CreateProcess gives the developer more control.
I don't know about particular issues related to Vista OS.

Hello,
i have the following problem (i think it is a beginner question but i hope to get an informative answer!)
Actually i try to get the BatteryDeviceName of my notebook. I use the code snipped from the MSDN.
But at these step iam hanging because the DeviceIoControl returns a BATTERY_INFORMATION structure, because the InformationLevel (bqi) is set to BatteryInformation. BUT I want the BatteryDeviceName, so I changed the Information Level. Then the IOCTL_BATTERY_QUERY_INFORMATION should return a null terminated unicode string.
My question is how can i store this ?string?
Here is my code:
BATTERY_INFORMATION bi = {0};
bqi.InformationLevel = BatteryDeviceName;
if(DeviceIoControl(hBattery,IOCTL_BATTERY_QUERY_INFORMATION,&bqi,sizeof(bqi),&bi,sizeof(bi),&dwOut,NULL))
{
MessageBox(NULL,L"#8 - IOCTL_BATTERY_QUERY_INFORMATION ... OK",L"",MB_ICONINFORMATION);
MessageBox(NULL,L"[BatteryDeviceName should be here !!!]",L"",MB_ICONINFORMATION);
}
As you can see i need to replace the bold line or more to store the String.
I hope someone can help me.
Thanks,
gabbana

Maybe something like this:
wchar_t szBatteryDeviceName[260];
bqi.InformationLevel = BatteryDeviceName;
if(DeviceIoControl(hBattery,IOCTL_BATTERY_QUERY_INFORMATION,&bqi,sizeof(bqi),szBatteryDeviceName,sizeof(szBatteryDeviceName),&dwOut,NULL))
{
...
}

Great thank you, but i have one problem:
If I use the szBatteryDeviceName in the MessageBox, he prints the correct batterydevicename but adds a part of the application path, so i think it ignores the null terminated string ?
|
|
|
|

Interesting - I wouldn't expect that.
I guess you could add the null terminator yourself:
wchar_t szBatteryDeviceName[260];
bqi.InformationLevel = BatteryDeviceName;
if(DeviceIoControl(hBattery,IOCTL_BATTERY_QUERY_INFORMATION,&bqi,sizeof(bqi),szBatteryDeviceName,sizeof(szBatteryDeviceName),&dwOut,NULL))
{
szBatteryDeviceName[dwOut/sizeof(wchar_t)] = 0;
...
}

Okay,
now i tried this with another type. I only get -1 as seconds, i am not sure if this is for a constant that the estimatedtime value is not available, but is the way correct for getting them:
estimated time should return as an ULONG.
ULONG estimatedtime;
bqi.InformationLevel = BatteryEstimatedTime;
DeviceIoControl(hBattery,IOCTL_BATTERY_QUERY_INFORMATION,&bqi,sizeof(bqi),&estimatedtime,sizeof(ULONG),&dwOut,NULL);
wchar_t szestimatedtime[260];
wsprintf(szestimatedtime,L"%d seconds",estimatedtime);
MessageBox(NULL,szestimatedtime,L"",0);
Thanks for help!
bye,
gabbana
