The user sees settings for each individual server, when he chooses one. But if he changes this settings, i don't want to loose the last servers settings, so i want to ask him if he wants to save them.
I did override the tostring() method and i still don;t see nothing on screen, but the items are there, since the listbox lets me choose from them.
I repeat, i don't know if i choosen the right control(listbox), I just wan't the client to see a lot of names( server names) and if he chooses one of them, he can change server settings. If I add the controls to the form directly, i loose a lot of support(scroll suport if there are many servers, and when i choose one of them it doesn't look as good as it would in a listbox)

I would add a few buttons (Save, DontSave,Revert), all disabled initially.
When a server gets selected, show its settings.
As soon as a setting is changed:
- enable those buttons
- diasble the chooser control (ListBox, ComboBox, whatever)
Now:
- Save would save the settings
- DontSave would not save the settings
- Revert would restore the original settings
and each of them would then go back to the original state: chooser enabled, buttons
disabled.
And yes I would prefer a ComboBox over a ListBox in this approach.

When I click on a cell in the datagridview, i want to get the data in that ROW and pass it as a parameter list to a secondary form.
and fill it with that row's data. Can anyone help I have no idea how to do this.
the steps will be:
1. click on a cell in a row
2. get the data in the row
3. click an update buotton on the current form
4. second form will open with card.ShowDialog() in the update-click event
5. the row's data must now appear on the card form(second form).
Thanks alot!!!

You need to catch CellClick event and extract index of row which contains the clicked cell from the parameter the event gets. Then you will be able to get all the data from that row

Hello!I`m trying to connect data from a specific data field in my database to a TextBox, by using the SELECT statement, which should allow the user to enter the IDNumber of the concrete set of data in one TextBox and then, by clicking on a button, to get the concrete data in another TextBox.
E.G.
TextBoxID - there you are entering the IDNumber of the concrete set of data
TextBoxCompany - returns the name of the company under that IDNumber, after clicking the button
I would be most grateful to anybody who would be kind enough to help me.Thanks in advance!

You basically want to write SQL, or a stored proc, that takes the number and returns the company name. Then you can set the text of the textbox to what you want. There is no automated way to do this. Ideally, you'd write the SQL code in a data layer, which you then call to get back the string you want, but if it's a quick and nasty app, you can probably get away with putting it all in one place. Just remember that many quick and nasty apps, turn into major undertakings, I always prefer to architect everything well from the start.
I assume you know how to write SQL and call the database, and were just hoping for an automagic way to do this ?

Hi ,
I`ve got a basic doubt about WinForms ...
Is it possible to create a form that has no client-area at all , but only a menubar that stretches across the entire width of the screen ?
The method i tried was to set the client area property of the form to (ScreenWidth,0) but it doesn`t work (a little strip of the client-area in grey is still visible below the menubar).
If its not possible to do so,is there some basic concept here which i`ve missed out on ?
Thanks in Advance

If you change the fromBorderStyle to None you will only have the menu bar left.
Hope that helps.

Hi Ben ,
Many thanks for replying ! I created a simple Form with a Menu & set the FormBorderStyle to None so this removes the scroll bars, system control box,min/max/close button etc...
But a grey area (which i think is the client area ) still persists just below the menubar.
I`ve tried working with the form height, size,clientarea and autoscalebasesize too , none of which works 
An alternative way i found was to override CreateParams and fiddle around with the WS_BORDER,WS_CAPTION values but again , the grey bar issue remains.
I`ll be grateful if any1 can tell me a way in which i can make a BMP of this available (since i dont think images can be embedded in posts ) coz it`ll give a clearer idea of what exactly is going on
Hoping the CP wizards can help me out here !
thanks !

There is just one more thing to do. In the form properties set the BackColor to something like Red. Then in the form properties set the TransparentcyKey to something like Red as well. It doesn't matter what color you pick as long as these two properties are the same. That will cause the line to go away.
Hope that helps.

I'm working on a WinForms app which talks to a webservice. With an Ajax app you'd use an "updating" gif, which would disappear once everything had completed - I was wondering if anyone knows of a preferred/standard approach when dealing with WinForms?

If the updating via the web service is going to take a long time ie keep the user waiting, then ideally you should do the update on a different thread from that of the UI. In VS 2005 you can use the BackgroundWorker control for this purpose.
A quick and dirty solution would be to lock down the UI and use a PictureBox control to display the 'updating' gif as in Ajax or alternatively use a ProgressBar.

Hi guys,
i really need some starting advice for a gui ive got in mind.
I need a grid of "data cells" ( in which ill be able to draw text and images into. Cells should be able to automatically resize to its content. Cells are arranged
logically in rows and i must be able to add and delete rows of corresponding cells at runtime. Cells shall also be able to handle a mouseover events and be clickable (left and right, scroll etc.)
They whole gui shall also be able to be resizeable. Scrollbars shall appear if parent window is noth big enough to show all rows of cells.
To get an impression what i want here is an protptype screenshot:

Hi Guys and Gals.
I need urgent help with a Setup I am doing. The problem is I have an App.config file where all my connection information is stored. I am using a generic class that reference this config file. The problem is when I run my setup and trying to run the exe and try to log into my database I cant. Yes, I did change the referencing of my files to the location where my db's are stored. I can run the application from within .NET, but not as an exe.
Please help. My deadline is today. Your help will be greatly appreciated.
Regards,
Elizma

Didn't expect anyone to drop everything to sort out the problem. Thought someone might have encounterd a simular problem, and know what could have been my problem. It doesn't matter anyway. I sorted out the problem myself. Just got too busy to delete the message.
Sorry if it came across as rude, since it was not my intension. I was just under a lot of pressure to get it done urgently since the program had to be rolled out that day and as a last resort I tried to see if anyone here might be able to help.
Regards,
Elizma
P.S. I saw that most people post the messages like that when they need urgent help. I just followed the norm. In future I will not use those words again, since it seems you are the only one that took affence to it. So, once again sorry if that is the way it made you feel. Was not my intension.
