Re: launching application from html page

Hi vyjesh,

I think I understand now. What you need to do actually is to register your won URL protocol. Basically, when you type something like mailto: or file: windows looks up the URL protocol scheme and transfers the handle to the application registered for that protocol.

In windows XP it's pretty easy to create and register your own protocol. You would have to add a key in the registry under HKEY_CLASSES_ROOT\ and give it the name of the URL protocol you'd like registered. Let's say myproto. So you'd vahe something like HKEY_CLASSES_ROOT\myproto. Then on the default value for that key type: "URL: My_Name Protocol". Also, add a new value to this key and call it URL Protocol. Then add a new key to the myproto and call it shell. You don't need to make any cahnges to this key. Then under it, add a new key and call it open. Also, no changes here. Finally, under open add a new key and call it command. Now, change the default value for this key to: "C:\Windows\notepad.exe" %1. This will make your protocol launch notepad! Pretty cool huh?!

So your registry should be modified as foolows:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\myproto]
@="URL: Mikanu Protocol"
"URL Protocol"=""

[HKEY_CLASSES_ROOT\myproto\shell]

[HKEY_CLASSES_ROOT\myproto\shell\open]

[HKEY_CLASSES_ROOT\myproto\shell\open\command]
@="\"C:\\Windows\\notepad.exe\" %1"

Then you can try this link: myproto:test.txt and it should lauch notepad and attempt to open a text file, called test.txt... Wink | ;)

For further reading on URL schemes check this out, RFC 1738.

Clipboard issue.

How can I determine that the clipboard content was dropped to the target window?

I implemented a code which moves data between two application using the COleDropSource stuff. Since the data are moved (NOT copied) between the applications I need to know when can I remove the moved data from the source application. So the question is how to determine that the target application pasted/accepted the data from the clipboard (or the drag&drop finished) and it is safe to remove the source data.

Can anybody help me with this?
Thanks,

Abyss

That’s not a very good design idea. What if I the end user of your app have important information on the clipboard? Here comes your app and whips it out.

Your better off posting a user defined message from one app to the other to pass the data. Alternatively you can us IPC “Inter-Process Communication”.

Hi All

Could someone kindly let me know how to identify the currently highlighted (tabbed) button on a modeless dialog before it is pressed? I've looked at GetFocus but that seems to only apply to window focus. (Using MFC)

Thanks

A button is also a window (in fact, every control derives from CWnd so every control is also a window). So GetFocus will work Wink | ;)

Run batch-job from MFC-App without command-window

Snore28-Sep-05 1:25

Dear all,

I wrote an MFC-Application in VC 6.0 which starts a batch-job. When I use
system("start_socet -single data_convert -batch -s C:\\temp\\settings.set");
it all works perfect, but displays me a command-window, every time a new job is started.

In order to avoid the window, I tried it with "CreateProcess" (see code below), but always get back, that the process wasn't able to open a file (MSDN Error-Code Nr. 2)! Does anybody have an idea how to solve this problem?
For your info: Start_socet is a MS-DOS Batch-File, data_convert is an executable which cannot be executed stand-allone!

STARTUPINFO siStartupInfo;<br />
PROCESS_INFORMATION piProcessInfo;<br />
memset(&siStartupInfo, 0, sizeof(siStartupInfo));<br />
memset(&piProcessInfo, 0, sizeof(piProcessInfo));<br />
siStartupInfo.cb = sizeof(siStartupInfo);<br />
int rc=CreateProcess(NULL, "start_socet -single data_convert -batch -s C:\\temp\\settings.set", 0, 0, false, CREATE_DEFAULT_ERROR_MODE, 0, 0, &siStartupInfo, &piProcessInfo);<br />
DWORD error=GetLastError();<br />

Best regards

You could read the batch file,
then pass the things written there to ShellExecute()

Which file is unable to be opened, start_socet or settings.set?

Have you considered fully-qualifying the application name (e.g., c:\\some_path\\start_socet.exe)?

Just an idea, you might be able to use _popen()?

FILE *_popen( const char *command, const char *mode );

I'm not sure if it opens a command window or not. Or if has the capabilities to execute a batch file.

But it could be worth checking up.

Hello guys,
thanks for your hints!
I tried _popen but id didn't work! The perfect solution was to fully qualify the application name, which is a surprise to me, but it works! Thanks a lot David! Smile | :)

Here's the code:

	int rc=CreateProcess(NULL, "start_socet.bat -single data_convert.exe -batch -s C:\\settings.set", 0, 0, false, CREATE_NO_WINDOW, 0, 0, &siStartupInfo, &piProcessInfo);

And for those who didn't know: There's a flag "CREATE_NO_WINDOW", which is only documented in MSDN online and hides the console-window in a very easy way (but not for Windows Me/98/95)!

Yes of course ! If you create your class with ClassWizzard, you have a ComboBox in which you can choose 'Generic class' (or something like that Wink | ;)

No, if you chose generic class and do not specify a base class, then you will not derive your class from any other class. Good Luck.

change row height in ListCtrl report style

Hi,
I've been trying to change the row height for my ListCtrl without luck. It does change when I increase the font size, but I want to keep the same font and just increase the row size. I've searched the codeproject but all I can find are articles on how to do this for a List View Control.

Thanks...

you need to handle ON_WM_MEASUREITEM_REFLECT (reflection).
Override

BEGIN_MESSAGE_MAP(CMyCtrl, CListCtrl)
	//{{AFX_MSG_MAP(CMyCtrl)
	ON_WM_MEASUREITEM_REFLECT()
	//}}AFX_MSG_MAP
END_MESSAGE_MAP()

void CMycntrol::MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct) 
{
lpMeasureItemStruct->itemHeight=20;
}

FlexGrid

Mike Winter28-Sep-05 0:46

Mike Winter

28-Sep-05 0:46

I have a FlexGrid control in my dialog box, with the first row and column fixed. When I click on either the first row or column, the whole row (or column) is highlighted, with the first entry in the grid NOT highlighted. Is there any way to turn this off, so that the whole row is highlighted?

What I am actually doing is when column 2 is clicked on, a control is displayed to allow data entry. When column 1 is clicked, I want to select the whole row (which is happening), but the column 2 data entry control is also being displayed - how can I stop this happening?

Thanks for any help - hope you excuse my newbieness!
