Entire Screen Fits On The Horizontal Line?
Sep 12, 2009
I have resized the form by using the following code. what i want to do is that i want to fit the entire screen horizontally...so that the horizontal scroll bar doesent appear.....
Private Sub Resize_Form()
Dim cControl As Control
Dim i_i As Integer[code]..........
Which value do i change in the code that the screen squeezes horizontally ...? There are only two controls on the right side when we scroll....i think if the resolution is done correctly then it will fit in the screen.....but i dont know what chages should be made in the code.

Currently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.

Sometimes when updating the entire screen or moving around controls etc, there is some fairly bad screen flickering.

Since the map image is bigger than my screen resolution 1280 x 1024, a horizontal scroll bar is shown. I use Location x and y to place icons, but the problem is:placing an icon at location (0, 0) when the horizontal scroll bar is at left-most position is different from when the horizontal scroll bar is at right-most position...If I move scroll bar to x-axis(right) 10 thenplacing an icon at (0, 0), should be (0, 0) but it is placed at (10, 0).n this case, is there any different approach?

Feel pretty stupid for asking this but I'm looki to add a very simple horizontal line/bar/separator to my GUI for a small project.I'm using Visual Basic 2010 Express. Last time I did any programming was with VB6 and I'm sure you could do this easily with that version but 11 years is a long time.

VB.NET
Dim b As New Bitmap(Me.Width, _
Me.Height, _
[Code]....
But I need to edit it so that it only takes the a screenshot of my form. I'm not sure how to pass the absolute coordinates of my form's top most left corner and it's bottom most right corner.

I have a user who wants to print the form that is on the screen(the entire form not just the data) on the click of a button, is there a quick and easy way to capture it and print it. Kind of like a screen shot? I suggested that they could just do alt/printscreen and capture the form that way and print it but they want it all to be done from a print button for them.

I have a program and wish to generalise its appearance at startup on different machines. This worked OK until I moved it onto a Windows 7 unit with a 22" screen. The front page covers less than 2/3 of the screen. I know I've asked the system for 'working area' but could not find a reference to the entire screen which other applications seem able to use. How can I catch up with them? The code is from VB in VS2005. Is this my limitation?

how I would be able to print the entire portion of the screen which the form occupies,Basically, my problem lies in that the way I print now will properly print the form's buttons/labels/textboxes etc. But it will not print the WebComponent AxChartspace that I have added to it. So basically my form is partially blank.

I have a listbox where each line contains a short 3-4 character model number followed by a tab and then the product name the model number corresponds to. I also have a textbox which I am using to search the listbox.
The code I am using so far works somewhat, just not exactly how I would like. If I enter search text it will highlight the results in the listbox but only for the first characters, is there anyway to search the text of an entire line (index) of a listbox?
Right now I am using the following:
Private Sub txtSearch_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtSearch.TextChanged
ListBox.SelectedIndex = ListBox.FindString(txtSearch.Text)
End Sub

I am working on a program to match overlapping images together to make one complete image. This isn't for panoramic purposes, it is from a video game generated overhead map, so there is no perspective issues to deal with and the overlapping images (gained from screenshots while a player moves) should be pixel perfect (still running tests to verify this, but lets assume they are pixel perfect at this time).
1) I need to compare each new (small) overhead map section to the larger map, find what edge it fits on, and copy it over.On other forums I have seen people suggest taking the bitmap apart in the form of an array of colors, or 3 arrays per image for r, g, and b. I am wondering why this is done instead of directly going to the bitmap object and using GetPixel. Is an Array lookup significantly faster? Speed would be an issue with my program, I would like to do this match as fast as possible, and the overall map could become large, even if I keep making new map sections to manually paste together later.So, faster to loop through a graphic with getpixel, or faster to go through 3 two-dimensional arrays with r, g, and b, or faster to go through 1 three-dimensional array with rgb all inside it?
2) The bitmap object that contains the overall map will keep getting larger. What is the best way to resize that bitmap dynamically?I am thinking of just making a new, larger bitmap when I get near an edge, then using getpixel and setpixel to copy over the old bitmap to the new one. Is there a faster way to make a new, larger bitmap object containing the old one with the graphics class? I admit to finding the graphics class somewhat confusing in how methods on it affect the image object that is defined as it's surface...or something. There might be a faster way with graphics and drawimage, but is that really faster than a getpixel/setpixel loop? Finally, if I do store the graphics data in arrays instead of actual bitmap objects, would redimming the array be the best way? If I need more room at the 'beginning' of the array I would have to make a new array and then copy the data over shifted. And this might involve 3 arrays if it is best to use one each for r, g, b.

BTW this issue occurs in any MS office program when the VB.Net (or even VBA) is processing information.Example: In Excel, a worksheet is displayed on the screen. I start either, a VB.Net or VBA procedure and within 30 seconds the Excel worksheet (previously displayed) blanks out. In both VB.Net and VBA,ScreenUpdating = False. My expectation is that the previously displayed screen would stay static as if I left my desk to get a cup of coffee; came back and the same ole Excel worksheet was still there?Of course, setting VBA Screen Updating = False accomplishes two goals: 1) speeds up processing and 2) saves the user from seeing unnecessary "garbage-processing" steps.Why does VBA or VB.Net ScreenUpdating = False not freeze the screen at the time of its invoking?

I'm using VB in Visual Studio 2010
When I resize my form at run time (border set to sizeable) .Net automatically adds scroll bars.
I can pick the vertical scroll bar ok but on the horizontal scroll bar it always shows the resize cursor and so I cannot pick it.
Is there some way of controlling the zone within which the resize cursor is active or the active width of the border detection?

How would I get the width of a Horizontal Scroll Bar? I'm not talking about the Hscroll width properties... I know the default width in vista is set to 17 pixels. I'd like to know if someone has changed their scroll bar width to a custom setting. Does that make any sense?

I have a horizontal scrollbar on my form, and the form is longer (vertically) than the screen. What I'd like is for the horizontal scrollbar to always be visible at the bottom of the screen, no matter where the user is vertically. Right now, the user has to scroll all the way to the bottom of the form in order to see the horizontal scrollbar.

I have a DataGridView with, say, a half dozen columns on it; the right-most column being the widest (a description that might exceed the window's width). If the user presses the Home/End or PgUp/PgDn keys to navigate thru the data, it will sometimes scroll horizontally to the right, which is annoying. Is there a way to prevent this?
I've tried .ScrollBars = ScrollBars.Vertical(so there's no horiz scrollbar), but that doesn't solve the problem. I'm not sure how to make the 1st column be always visible - but even if I make it visible upon displaying the grid.I guess basically I don't WANT it to scroll horizontally, except when the USER scrolls.
