Hi, is there a simple way to convert formats like BMP GIF and so on to the JPEG format? How do I do this?
|
|
|
|
|
Yup, this should do it
Bitmap image( @"C:\mypic.bmp" );<br />
image.save( @"C:\mypic.jpg", ImageFormat.Jpeg );

I want to create a tabel with 3 columns and multiple row which can be filetered and sorted. The data is not located in a database.
Is the datagrid the correct coice of control to use? If not which should I use. I am concerned as all the examples I have seen seem to be link to a database. Does anyone have an example of non-database use?
Thanks,
Liam

Well, what's the table's filename extension then Liam? What kind of a table is it?

The data is not an external file so does not have an extension. The table will be constructed from a number of variables in the code. The first column will be a description (this will not change after initialisation), the second column will be updated periodically and the third colum will be the time of update.
Hope this clarifies things a bit.
Thanks,
Liam

Take a look at this article.[^] I believe it gives you an alternative to the DataGrid by allowing you to attach a data source to a ListView, something that .NET's implementation doesn't do. You should then be able to change the filter and sortby of the DataView.
The only reason you see examples linked to a database is that it's an easy way of populating the DataTable. You can certainly create the Columns, do a NewRow, set the fields, and do an AddRow yourself.

Depends on what exactly you want.
If you want an easy and straight way and your data isnt too big (lets say less then 100000 rows) then you can just pack your whole data into a DataTable and display it in the grid. This way you will have sorting and filtering capabilities right from the start. That the data isnt bound to any database isnt relevant.
For some extended filter functionality in DataGrid have a look at this article.

Hi,
I've wrote a .Net Remoting client-server application. I'm using a config file to connect the components and use the Ingo Rammer RemotingHelper class
http://www.thinktecture.com/Resources/RemotingFAQ/USEINTERFACESWITHCONFIGFILES.html[^]" rel="nofollow">
The problem is : I can't disconnect client from server (only when I exit the exe).
I disconnect client from server using
RemotingServices.Disconnect(ObjetMarshal);
but I have an error : "Cannot call disconnect on a proxy"
Thanks !

Hi Soke,
You can call the RemotingServices.Disconnect method on remoting proxies.
Guess the following link will help you.

Thanks for your answer !
But there is something I don't understand. In fact Disconnect method doesn't really disconnect client Ok for that but how than disconnect ?
I don't find the answer on the mentionned blog :s
In fact, I would like to unregister the channel on which i was connected (to have all my ressources free)
Thanks !
Sok
ps: i'm working with framework 1.1

Hi Sok,
The blog which i mentioned talk about RemotingServices.Disconnect method.
To unregister a channel you can use ChannelServices.UnregisterChannel method.
ChannelServices.UnregisterChannel(channelobj);
Thanks and Regards

Yes of course there is the ChannelServices.UnregisterChannel method
But my problem is than i connect my clients with config file and activator.getObject.. Then I can't find the way to unregister the channel

hi all,
I have done a C# Applcation with TextBoxes,Labels and DataGrid.Default Window State of the Form is "Normal".
Now I want to resise Controls in the Window Form when maximising the Dialog..
How can I do it?if any one knows it ,please reply me..
thanks in advance..

you can use the Anchor propriety of the controls to a certain degree. For example if you have a control Anchored to a margine, whenever that margine is moved the control will always keep the same distance from that margine. if the control is Anchored to two oposed Margines(left and right for example), when the parent control is resized, the control will increase his size acordingly so as to keep the same distances from the margins(in the left right case he will increase his width). Anchors work in desing mode too .. you should try and experimet with them there.
if you want more control you can handle the SizeChanged event of the parent control (this beeing in your case the main form).

Thanks for reply..
This Method is work successfully if one control in the Windows Form.
How is this implement to WindowForm exist with many Controls..?
|
|
|
|
|

hi
if we add many controls to the Application,and do Anchor for all controls,after that maximising several times, some controls are going to invisible.
that's the problem.
|

Sounds very strange. Never heard of that one. But I've experienced similar problems in other situations (I have a button on a tabpage that tends to disappear when I disable/enable it).
Do they appear again when you manually call Invalidate() on the form after maximising? Maybe that could be a workaround.

Probably not a very good way to do it, but you could keep checking for the mouse's position on the form by implementing a timer. If the location of the mouse cursor is within the control's boundaries then you know the mouse is over that control.
Hope this helps

G'day Folks,
I was just wondering if it is possible somehow to determine if an application is in focus or not. For example, an instance of ms excel is running, it is in focus, if its window is active. Reason for this is that I have managed to write a small c# application which can determine if an instance of ms excel is running, ie. it can be the active application or be minimized to the taskbar.
Therefore I was wondering if anyone can shed some ideas as how to I can determine if the desired application is in focus or not.
thanks
Vee
