I have a single form windows application and here is my question; When I set the property of the form's start position manually to centre parent or centre screen it starts up in the centre of the screen. When I do the same thing in the form load event:

Public Class form1

Why is the "Me" keyword not working. The error was "Syntax error"
I have an application, in which i have some windows forms and About form.When i show these windows, As of now they are coming somewhere near screen top left. But i want them to come at the screen centre.
View 8 RepliesAt the moment when i run my form1.vb program it runs in the top left of my screen, when i save it as an application and then open it from a shortcut will it still do this or will it open in the centre of the screen? In the designer it is in the top left of the screen, is there a way to move it here? as my assumption (which is probably wrong) is that the position it is in the designer is the position it is as an application? Is that right? and if it is how to i change the position in the designer?

View 4 RepliesI'm setting form sizes according to user screen resolution and I think I need design no smaller than 1024 x 768 these days. Using the following code I set my first form and use Anchor settings to resize and maintain controls. Does resize affect StartupPosition in other forms and what do you think is the best StartupPosition to Show the next (smaller) forms? I have a feeling I should have created child forms but simply added forms to the project as I needed them. For example, the first code example does not take account of the WIN7 Task Bar.
HTML
Dim x As Integer = My.Computer.Screen.Bounds.Width, y = My.Computer.Screen.Bounds.Height
Me.Size = New Size(x, y)
A smaller form loads with the same code slightly varied, but the reduction is not taking account of the screen resolution. Is there a way of reducing by percentage?
HTML
Dim x As Integer = My.Computer.Screen.Bounds.Width, y = My.Computer.Screen.Bounds.Height
X = X -100
y = y - 100
Me.Size = New Size(x, y)
Basically I currently have the following code which enables me to print the form perfectly.
CODE:
However, with the coding above on the print preview the form screen shoot/dump isn't centred. So I was wondering what would be the way to go about doing it? This is using the printform in the power packs available btw.
Also I figured it might be using height/width/location/margins etc, but I'm not to sure how one goes about assingning values to them. Like the two above I commented don't work.
i have managed to get the form to resize according to the screen resolution but now im struggling to centre the objects on the page?

View 3 RepliesCan we set the windows form resolution according to pc screen resolution and even the control should be adjusted...
eg.
My screen resolution is 1366 X 768
and my form size is 1254, 709....but I want it so set according to the screen and it will be dynamic...
if I transfer my project to some other pc with lower or higher resolution it should be adjusted....
and suppose I have few controls on the form...will that also be adjusted??
How can one set the screen size? As with the task bar, by incressing the size sets new limits when maximizing an application's window. How can I tell the system what would be the demensions of the desktop screen: left, top, width, height?
View 5 RepliesI build an application that is designed to work on a screen resolution of at least 1280x1024. So therefore, when my application starts, I would like for it to check the current screen resolution, if the screen resolution is not what I specify, then a message will ask whether the user wants to change it, if he clicks yes, then the screen resolution will be set to 1280x1024 and then it will reset to the original when the application closes. However, if the desired screen resolution is not available, then an error message will pop up.
View 2 RepliesI am working on an application using vb 2008 express. I have built test programs over the past few weeks and shared them for feed back. Today when I finished some work, I built another test application, but when I install it the start-up screen maximizes but is set between one and two desktop icons from the top of the screen.
In debug mode it looks fine. In the past it looks fine. Each time I start the program the screen is in a slightly different location. It is set to start maximized and to the best of my knowledge, I did not change any settings in the property area. I have tried loading on three computers and the results are the same. Any ideas on what I could have done to produce this strange result?
I am developing a point of sale for a buddy.The system it will be on will be running nothing but this application. The system SHOULD always stay at 1024, 768 but i like to plan for problems.What I would like to do is on form_load change to 1024, 768. On exit, (for learning sake on my end) I would like to have it set back to the default.
View 6 RepliesIn Microsoft Access there was an easy method to turn off screen updates by setting Echo = False. Is there an equivalent in VB.NET for WinForms? I've got a situation where I'm trying to prevent users from seeing controls flickering while they're being updated. I could probably solve the problem by coding it differently, but would rather avoid it if I can.
View 2 RepliesI have a panel, 80 pixels wide and 720 pixels high. However, this panel will stretch to whatever height the user's display is at as the form border style is none and the form is set to maximise.

View 6 RepliesBTW 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 have a tough situation that I don't really know how to code. I have one main list of point that contains all the points on a picture that are black.(1point=1pixel) I need to group all the black pixels that are less than 15(more or less) pixels away from each other into one Separate list. In the end I want about 5 lists.
What I said above is what I think is best to detect the centre of a shooting target. This information is just for those who think they know a better way. Each card has 5 targets on it and I need to detect the centre of each target. Ignore the sticker on the top target, in all cases the top one will look like the rest.

So I'm trying to take a screen capture of the windows form and display only a certain specified area of that screen capture in a picturebox on a different form. Kind of like this. First, take the screen capture of the form: Then get a specified area of that form through x,y coordinates or something and display it on a picturebox on a separate form.
I have read that VB .NET in earlier versions limited the FORM size to that of the development machine screen resolution.I am hoping that there is a way in the current VB 2010 to get around that.However in my attempts to make the form larger, it always resets itself to the screen height on my develoment machine.Is there a way to get around this and have the person be able to use a scroll bar to move down?The data I wish to show actually has two screens worth of information but the stuff in the scroll down section would be used on a limitied basis so scrolling will be useful rather than having to recreat the screen to show less data at one time.
View 2 RepliesI am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.

View 6 RepliesI've run into a little problem recently. My computer has two screens sitting side-by-side.
Here are the dimensions for my first screen: {X = 0 Y = 0 Width = 1280 Height = 1024}
Here are the dimensions for my second screen: {X = 1280 Y = 0 Width = 1280 Height = 1024}
My form saves its position on exit into the Registry. Whenever I start my application, I set its opacity to 0 in the constructor and it goes to my first screen. While its opacity is at 0, I then move it to its previous location (1280, 0) like this:
thisForm.Left = X
thisForm.Top = Y
Where X = 1028 and Y = 0.
I place a breakpoint directly in front of those assignments and when I hover over thisForm.Left, it = -4. Whenever I hover over thisForm.Top, it = -4.
Sure enough, when my form comes up, it's in my first screen.
For those interested, I've now worked around it, by doing some additional testing. What caused it: My Window State was Maximized. Solution: If before I set these positions, I change my Window State to Normal, the form moves. I can then maximize it while it's on the second screen and it remains there. why I can't move my form while it's maximized? It's more for curiosity than to find a solution, since the work-around is actually working quite well.
