    - Testing / Validating a connection string I am currently developing a winform application that requires a connection string to be entered by the user. I would like to validate this connection string. One way to it would be to perform a naive SQL query like "SELECT 1". Is-it a good idea to proceed that way Is there any build-in or recommended mechanism to validate a connection string What would you suggest Thanks in advance, Joannes Lokad.com , sales forecasting Tag: Windows Forms Data Controls and Databinding Is DataBindingComplete the proper place to add user columns Windows Forms

    - Import 16x16 bmp & use as an icon for forms Can someone please tell me a step-by-step procedure to: a) take a 16 by 16 pixel bmp & import it into VS 2005 (using VB) b) convert it to an ico file c) cause some forms in my application to use the new icon. This seems like it should be very easy, but I have burned a ton of time on it with no success.

    - Intercepting/Overriding Paste behavior on ComboBox In C#. I need to intercept and override the default behavior when pasting text into a system.Windows.Forms.ComboBox control. I need to translate the text before it gets put into the combobox (replacing some characters with others, for example). I am unable to find any relevant Paste events or overridable methods. Anyone have any cool tricks/ sugestions on how to do this. I tried grabbing the WM_PASTE (0x0302) message in a WndProc override, but iI never see the message. Evidently pressing Ctrl+V in a ComboBox does not generate this message (or it's getting consumed before the WndProc on the custom ComboBox ever sees it.'

    - radiobutton functionality in the ToolStrip using ToolStripButtons...? given the following Form1.Designer.vb that have all the ToolStripButton's CheckOnClick = True. I have been asked for this to have radio button functionality, ie only one button can be selected at a time. The way this is currently working is that if an item is selected, the background color of the button changes. A complaint is that when the mouse hovers over another button that button's background color also becomes the same color as the selected button. It has been mentioned that this has been confusing to them. Which button is really selected Has the hover selected both buttons I am also seeing that this is not providing a radio button operation. If I select a second button, that does not toggle the value of any previously selected button(s).

    - detect user inactivity (idle, timeout) Do you actually need to detect activity in each specific window Or, are you just interested in inactivity of the entire session (e.g. no keyboard or mouse input for 60 seconds) If checking the entire session is okay, take a look at the GetLastInputInfo call in user32. You could call this every second or so from a timer, and as a bonus, that will occupy less resources than using hooks.

I've stepped through and after Form2 closes, it just jumps back to Form1, then straight to the Mainmenu form. regards.

I want to create child forms in an MDI parent form that have thin borders and are sizeable. Can I make a sizeable window with a thin frame using this window style technique Can we separate the ThickFrame property and the Sizeable properties Why should all sizeable windows have thick frames - we want more choice!

    - Extended OpenFileDialog Hi everyone, I'm trying to make a custom OpenFileDialog that select files and folders, the original one just returns the selected files even if I select files and folders in the dialog. So my ideia is to make a custom usercontrol to allow the openfiledialog to return both selected files and folders (once the dialog allows selecting folders maybe I can return folders to) This is an ideia but I don't know if this is possible and if is, how to handle the ok button click event.

    - Saving and restoring Windows form states I'm developing a windows form application which allow users to query the database. When users press the reset button, the windows form will go back to the initial state(resetting all the controls in the windows form to initial state) I've thought of the followings to achieve this 1) Put all the resetting codes inside the reset button event. 2) Use serialization 3) Close the windows form and create a new windows form. But I think there may have some better ways.Can anyone advise me Thanks Tag: Windows Forms Data Controls and Databinding Is DataBindingComplete the proper place to add user columns Windows Forms

However, I am unable to figure out how to display this on another monitor.

But the problem with this shortcut is that whenever i right click on it & go to property, its Find Target and Change Icon buttons are disabled. The difference that i have observed between other standard applications shortcuts and this one is that its Target Location on the property page is not set which are set for other ones whereas Target property just points to the name of the application.

    - C# How do I keep GroupBoxes seperate? A possible reason why the bottom one may have been controlling the others is that you actually made them contained inside of it. You probably can't drag the group boxes directly to the right location using the mouse. Instead, get it close and then tap the arrow keys to align it exactly (or use some of the alignment tools). That being said, it's still not a very elegant solution. A tab control would probably be my first choice. You can even hide the tabs so it doesn't look like a tab control. See nobugz's post on this thread for an example. Tag: Windows Forms Data Controls and Databinding Is DataBindingComplete the proper place to add user columns Windows Forms

Hi,

I need to add some columns to my table so that I can use the maskededitcolumn control. I am doing this is the DataBindingComplete event handler. Is this the proper place

A second question is I have noticed that the DataBindingComplete event gets called many times. Can someone define under what conditions DataBindingCompleted is fired

Thanks,

Jerry
