I have a form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.
View 2 RepliesI've been investigating and experimenting with the code snippet on this page: [URL] - with some rather undesirable and wacky results being produced.
Why do I need this? I am attempting to adapt this snippet to suit my needs for a day/night system in the game I am working on. I am sure that the correct results can be produced with this snippet, but at the very least I need some guidance as to how I can achieve what I want.
I've developed an application that acquires images from my Logitech QuickCam Pro 9000 using WIA. The problem is that I cannot figure out how to adjust the quality of the image taken by the camera. The camera has a 2MP lense, but the program will only acquire a picture of 320x240 pixels, which is the lowest resolution the camera has. How do I tell the camera to take a picture at one of it's other resolutions? IE: 640x480, 960x720, 1.3MP, or 2MP?

how i can refresh my main form background image once a user picks a different image as the background.I have 2 forms namely Form1 (main form) and form2 from where the user can select the image he or she would like to set as the background image of form1.But the problem is that after selecting the image file from form2,when form1 is opened the background image doesnt change and remains the same as before.Only when the user ends the program and re-runs it again the image changes.
I tried
Form1.reload()
I have a splash screen and want to test the loading bar. The % of loading are in 11 stages (0-100% in 10% intervals) and I have 11 different images. What i'm trying to do is set my picturebox.image = to the resource image and then wait 1 second then set picturebox.image to the next resource image. What i was doing is on the SplashScreen.Show method [Code]. What happens is that the picture box doesn't refresh with the image until the last image has been loaded from the procedure and the end of making the thread sleep completes. (this worked fine in VS2005). How can I make it load up the image, redraw the picturebox and then make the thread sleep for 1 second in VS2008.

I'm having trouble adjusting the font style in a RichTextBox and I've seen a few different approaches that talk about single attributes (like toggling bold on and off)... but I'm trying to make it so that my font class can adjust any attribute (bold, italic, underline).
I realize that Font.Style is a set of Boolean flags (a bitfield?)... but I'm not sure how to handle the attributes all at once.
Here is the troublesome code:
Public Sub ModifyFontStyle(Optional ByVal Plain As Object = Nothing, Optional ByVal Bold As Object = Nothing, _
Optional ByVal Italics As Object = Nothing, Optional ByVal Underlined As Object = Nothing)
[Code]....
What is happening to the font? The text should be underlined and in italics not strikethrough...
Is this a logic error or a simple misunderstanding on my part?

View 9 RepliesIt seems there is no easy solution for adjusting a specific format of a used font e.g. for Text. As I understood in order to change any part of the used format we need to use New Font(...) form of implementation which looks a bit odd to me.
TextBox1.Font.Bold = True
which needs to be rewritten as:
TextBox1.Font = New Font(TextBox1.Font, FontStyle.Bold)
which is no reason that I can see why it should be hard like that.Anyway, here is my solution for adjusting the font style using four CheckBox controls (i.e. BBold, BUnderline, BItalic and BStrikeout).Preview is a TextBox control.
Private Sub SetFontStyle(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BBold.CheckedChanged, _
BUnderline.CheckedChanged, _

I've a form set to size 1240:750. On my PC where I've VB2010 installed, the screen size is set to 1680:1024 and the form can be viewed fine but on a PC with screen size set to 1280:1024 (higher than the form) the form in question is cropped almost a third of it. To adjust the form to everyone screen size I set the below code at load with no avail.
'Autosize form to screen
Me.Height = (SystemInformation.PrimaryMonitorSize.Height) * (0.9)
Me.Width = (SystemInformation.PrimaryMonitorSize.Width) '* (0.9)
Me.MaximumSize = New System.Drawing.Size(Me.Width, Me.Height)
Me.MinimumSize = New System.Drawing.Size(1240, 750)
I have a windows form which contains a group of panels in a flowlayout control. Each panel has a button acrossthe top which is always visible and clicking on it expands the panel to view the other controls on it. clicking on it again shrinks the panel back to the size of the button. A simple form of menu. The flowlayout control has autoscroll enabled and as enough panels are resized (opened) they obviously are too big for the form and a scroll bar pops up.To get the most recently opened panel in the viewable area I use
FlowLayout.ScrollControlIntoView(pnECBF)
where pnECBF is the panel just resized. This works but places the panel at the bottom of the form i.e just in the visible area. I want the user to be able to see the panel AND the next menu button which is on the subsequent panel. So basically what I want is the panel into the visible area +25 pixels for the next panels menu button.
I'm trying to make a string inputted on a separate form's text box adjust the value of a string on another form. Is there a way to do this rather than exporting the data to a file and retrieving it on the other form?

Does anyone has a sample code or idea for cutting and adjusting a picture size when it is uploaded thru picturebox?
For example..
1. Picturebox size on winform = 150*150
2. A picture size = 1024 *800
3. I want to be able to cut 150*150 out of 1024 *800 and upload it. I wish the cutting and adjusting size is possible thru winform.

I am trying to design a report where one filed can be multiple lines and the other related field should be located below (See attached)
address may be 1 one or more lines, city state zip should be located just below.
I already have the field set to can grow, however the spacing is the issue. How do I make the spacing adjust at runtime depending on the number of lines in the field. I can space it to say 3 lines, but if the address filed is only 1 line it leaves a 3 line gap.
Once I read the property for DataGridView Column which allows Grid Column to adjust as per the data width. I can not recall it or find it.

View 9 RepliesI have created a simple VB.NET application with one form and a few modules. When a user clicks on a run button of the form the application starts and goes through differet cycle, while updating the user on status bar, runs for less than four hours.
The application works fine, it gives desired result. However, it is not able to refresh the user form, meaning status bar remains same after some time (it suppose to increment). Even when I take mouse on the form it shows timer symbole instead of default one.
My application commands another device using GPIB. Basically, PC running my application commands the device. If I look the display of device it gives correct information.
