Check If A Key Is Currently Pressed?

Feb 4, 2010

How would I check if a key is currently being pressed?

Also how would I detect if a key is pressed without using the KeyDown event. The reason I am not using the keydown event is when the user holds down a key it calls the event, waits a second than keeps calling it. I do not want the wait period if a user is holding down a key.

.net - Not Checking For Control Key Pressed Properly?

Apr 5, 2011

I got this timer tick function: Private Sub controlTick(ByVal sender As Object, ByVal e As EventArgs) Label2.Text = (Control.ModifierKeys = Keys.Control) End Sub

That is supposed to make my label say "True" if I am currently holding down the Control key, and "False" if I am not.But, how come my label is always "False"? What is interesting is that if I press the Control key at lighting speed a bunch of times I can see for a fraction of a second "True", but immediately turns to "False".

Timer ticks every 50ms.

Detecting The Key Pressed, When Working With Web Browser Control?

Feb 9, 2010

I am working on an application and I need urgent help. One of my forms contains a web browser. I need to detect if F3 key is pressed while the web browser is active, so a dialog box will appear for a particular functionality of the application. But unfortunately web browser control does not have keyup, keydown or similar event to help me detect if the F3 key is pressed.

Combo Box Control - Button Is Pressed, The Current Data Is Stored Into The Array?

May 28, 2009

I am working on an inventory managment project for a lumber mill. I am currently writing a piece of software to be used on the sorting section of the mill. The problem I am having is when a stick of lumber needs to be cut down in lengt. My current setup has a combo box that is populated with lengths of lumber that we might have (2' - 60'), a "Add" button and a data control (homemade solution with lots of labels, and panels).

The user will scan a tag into the system, and the system pulls up the info from the db. If the piece need to be cut, the user will select the length of the cut, and click the add button. The system will then populate the first line of the data control with the info from the cut (previous piece info, and new length). It also populates a pieceObject struct. This happens for any additional cut that might happen.

The problem I am having is that everytime I press the "Add" button, the length variable will update every length in the piece array.

Here is a section of the code I am dealing with.

piece is a lumberPiece, and pieceAry is a array of 15 lumberPieces

Each time the add button is pressed, the current data is stored into the array, and then the pieceNum is incremented.

VS 2008 - Check If A Control Has Been Validated Yet?

Jul 28, 2009

Is there anyway to check if a Control has been validated yet?I have some code that I want to run when the Selected of a TabControl fires off.The thing is, that I have TabPages added to the TabControl at the beginning of runtime, which then triggers the Selected event before the control is completely existent, which means the Sub I have that also happens to reference the control during that event errors out because there is technically not an instance of the control completely finished building so it says I don't have a correct reference set to that object.So basically, I want to be able to check in the Sub if the control has been Validated, or maybe even created or whatever is going on.

Version Control Add-In And Allows Multiple Check-outs Of A File?

Nov 23, 2010

I'm looking for Version Control software that works with VS 2008 & allows multiple check-outs of a file, merging the changes as each version is checked back in. Obviously this would require manual resolution when two programmers changed the same procedure,but that rarely happens here-what usually happens is we have two (or more) programmers working on different parts of the program that happen to occur in the same file so only one of them can actually do their work at a time. Highly inefficient.

We're currently using Visual Source Safe, by the way. I 'inherited' this so I'm not *absolutely* certain it can't be configured for this, but if so none of the older programmers (in terms of time in this office) know about it. I think they used a home-grown program. Besides, I haven't been able to remember who I heard about it from so remembering that really isn't a help-at least not yet.

Error Provider To Check Control Validation Until Save Event

Jul 15, 2009

I am writing a User Control. Into each control I am loading a custom biz object. Because the biz object implements IDataErrorInfo interface I am able to use the ErrorProvider control on the user control.

I am binding the ErrorProvider to the biz object like this:

Me.ErrorProvider1.DataSource=MyBizObject This is all working perfectly EXCEPT. The validation is happening (and therefore I am displaying the blinkey error signs next to all feilds) as soon as the User control is loaded into the host form.

Each biz object implements a SAVE method and I want the validate to not happen until the save event is triggered on the biz object.
