Is there a property setting that prevents an empty row from being displayed in a DGV? I have a DGV that is populated manually, the dataset that contains the data has 2 rows in it. The DGV contains those 2 rows of data plus an empty one. The return value of the DataAdapter Fill is also 2.

I have a VB.NET form that takes up the whole screen. On Windows XP, the taskbar is not displayed when moving the mouse to the bottom of the screen. I have auto-hide set, and the taskbar is not locked. I tried the same thing on a Vista computer and it works fine. What am I missing on Windows XP? I need the auto-hide feature to work for my app like it does for other Windows apps.
View 1 RepliesI added an splash screen to my app. Then in the project settings I selected it to be used for the splash screen. Now my app won't close when I try to exit my app. I have 'When Last Form Closes' selected for the shutdown mode. So I'm guessing the splash screen is calling Hide() instead of Close(). I can't find a way to get access to the splash screen object so I can try callling Close().

I have created a custom combo that automatically drops when the combo receives focus. When the user uses the mouse to click on another control or the Windows Form the combo list is undropped but the click on the other control is never fired. Is there a way to avoid what appears to the user as a need to double click?
I use the 'TransparencyKey' feature on my form to make a 'Panel' control transparent so i can see a program thats running underneath my form. If i try and do a screen grab (Capture a picture) of my form it only grabs a image of the background of my desktop and the program below and not my form.
If i use the normal Windows 'PrtScrn' key to grab a still image it manages to capture my form and underlying programs fine. This appears to be a limitation of transparencykey because as soon as you disable/remove it the screen grab works fine on the form. how to resolve this problem as removing the 'TransparencyKey' feature is not a option as i require this for my program
see the attached image for a better description of the problem
Image on 'Left' shows the transparent window viewing the desktop and program beneath. Image on the right shows the captured image and it completely missing the form and transparent window from the shot.

View 2 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

This must've have been asked before but I couldn't locate it. In a mixed code project (VB and C#) we were debugging some old Visual Basic code where a statement as follows could be found:
If Request.Params("xxx") <> "" Then
'do something
I considered this a bug as Request.Params could be null, in which case the statement would've become false which wasn't the idea. So I thought. I just found out, -- probably for the tenth time and I will keep forgetting -- that the following two statements are not equal, while Nothing in VB should be equal to null in C# (thought I):
if(String.Empty == null) // always false
If String.Empty = Nothing Then ' always true
Should I dismiss this as a typical Microsoft backward compatibility effort, or should I consider this a huge error in the VB.NET compiler? Does anybody know the Microsoftean opinion on this oddity?

In vb.net (2008), I want to be able to control when a contextMenuStrip (context menu) is displayed. I don't want it to always appear when the right mouse button is clicked...only when certain criteria within my program are met. I figure I would use addHandler but I'm not exactly clear on how to completely control the opening of the contextMenuStrip. I know I would issue a call to the "open" method to render the contextMenuStrip. However, I am unclear as to how to completely take over control of when to render the contextMenuStrip.

I was wondering how i can then clone what is now on that panel to another - i have tried: panel.DrawToBitmap and then painting the resulting image on the other panel - but this doesn't work
oh and also the panels may not be the same size ... so in this case the result would need to be "stretched" or "shrunk"

I have a datagridview with 3 displayed columns and 10 columns overall. If I run the program the gridview start with the first column visible and displayed. Now i want to scroll with the vertical scroll bar.
If i click on the "right" button of the scroll bar
my DataGridView1.Scroll - event
says:
DataGridView1.Columns(0).Displayed=True
DataGridView1.FirstDisplayedScrollingColumnIndex = 1
So this means "yes, the first Column is displayed but the first displayed Column is the second one!"

I am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.
