Hi,
I'm trying to create a windows application which has non rectangular shapes. (Some thing like Media player). There is an article in MSDN, but they mentioned that there are some issues. I'm also facing them. So please advice me on how to do this?
MSDN link :http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskCreatingNon-StandardShapedWindowsForms.asp
My mail address is amilacp@gmail.com
Thanks,

To achieve this u have first create a image which contains of the shape u want to give to ur application, and set the outer region with some color (Black), now set the background image of the form to this image, set the
transparency key to the color that u have set to the image's outer region
i.e. Black, Change the formborderstyle to None,
this will work for u.

Pramod

From MSDN
Note Monitors set to a color depth of greater than 24-bit can have display problems with certain parts of the form not being transparent, despite setting of the TransparencyKey property. To avoid this problem, ensure that the monitor's color depth is set to less than 24-bit in the Display control panel. When developing applications that feature this transparency, keep in mind that you will have to make your users aware of this issue.
This is the issue i'm facing. Please advice.

Hi,
I have mapped the following code:
public long GetDlgText(long DlgId, long FldId, long Row, long Col, BSTR* Text);
to:
unsafe public long GetDlgText(long dlgid, long fldid, long row, long col, string* text);
but, off course, you cannot use * on string variables (all the rest, no problem, but string, it seems, is a 'no, no')
know I'm not sure how C# passes parameters.
I would think that it passes the value because you can use the ref keyword without the unsafe statement and I thought ref string mystring was the same as CString &mystring for example.
So is it enough for me to just write string text instead of string* text and if not, what should I do then?
[EDIT]mm, know I'm at it how can you map the keyword FAR?
eg.:
public long FormatSecProjCoord(double easting, double northing, string* e_str, string FAR* n_str){<br />[/EDIT]
tnx!
No hurries, no worries.

Your mappings should look like this.
public ing GetDlgText( int dlgid, int fldid, int row, int col, [MarshalAs(UnmanagedType.BStr)] string text );
You don't need to map the key word far. The interop marshaler takes card of that.
I hope this helps.

Dude,
thank you so much, I was already looking into the attributes, but couldn't find the appropriate (is there a link to a page with the possibilities? I couldn't find one)
thanks

Im using serial port communication in my application.
In the firmware side i sent 1000 data/millisec.
the theme of my project is "No lose data in capturing time"
how can i maintain the Buffersize. i cant get all the data
in my application running time.
Send reply

Explain more fully for a start.
My guess is that the trouble is with the firmware side of things since our company ran some tests of MSComm vs .NET vs other third party controls and found the MS ones behaved the best in all our tests.
When writing RS232 drivers for firmware, don't to any processing in the interrupt handlers, just flag that the data is ready, somewhere else in your program you must retrieve that data ASAP otherwise it'll be overwritten. Buffersize plays a small role in RS232 comms compared to the other problems which can occur.

hi Ed.,
Thanks for ur reply. Actually main theme of my application is data capturing. In the firmware side they will send 1000bytes / 3 millisec.
I capture the data and do some process and display in screen with some GUI.
They will put some index for all data. Every time i lost some bulk of data during the integration. how to solve this problem
need reply

Have you tried buffering the data on the firmware side and sending it to the PC at a lower baud-rate. 333,333 is a very odd and high baud rate for a serial port. If you need such a high speed then you're probably better off with a USB port.

hi Ed.,
In firmware side only they sent 1000/3millisec. Im using 115200 baudrate.
And tell me how to read the data from USB port method. Now im using SerialPort method.

Hi there,
I noticed that the "Bytes threshhold" that fires the read bytes event, does not fire as often as you would wish. in order to read the bytes fast enough, rather use a timer to start the readbytes event in a timer loop, instead of waiting for the serial port read event to fire.

Hi, i have to get the bound of a photo.

different.
How can i have automatically the bound of my jagged rectangle?
Exits any method to do this?
Thanks.

Wht have u used to display the Photo?

yes i use a pictureBox.
how can i use the region for my purpose
I have to recognize the profile of my rect
direct from the photo.
do you think that is possible?
thanks. nik

If u are using a PictureBox then the picturebox is always in a rectangular
form, u can use the Region property of the picturebox which returns an object
of the System.Drawing.Region, the u can get the bounds of the Region
using the GetBounds method of the region object
Hope that works for u

Pramod
