I am new with VB.NET 2008 and I would like to know how to make a project so the forms will show correctly on various sizes of monitors. Do you have to put code in every form for this?
View 1 RepliesI am using VB 2008 Express: The template forms for splash and about screens have a background image
consisting of 3 circles (orange, green and blue).I would like to use this image throughout my app,
but can't find it anywhere.Does anyone know where this is located in the visual studio program
structure?
All I need to do is scale a panel to my co-ordinates X = 0-100 and Y = 0-100 and then plot a point (PSet?) at 50,50.

View 1 RepliesFinishing off my control, but I now found a nasty problem. When the user holds the 'Ctrl' key and scrolls the mouse scrollwheel, the control is scaled. I do not want that, since it would make the Font size fail.
I previously made it reset the scale on Control up, but that is just not a very elegant way:
Me.ZoomFactor = 1 I do not want the text scaled at any time, not even while the user is scrolling and it resets afterwards. I got to overriding the 'ProcessCmdKey' but no idea how to catch a scroll or zoom event.
Any way of disabling the RichTextBox scaling (or zooming) so it does not even occur? I have a control that inherits from the RichTextBox.
I'm building an application that essentially attempts to fill up all of the user's screens with a maximized form. On most machines this works. I'm simply using My.Computer.Screen.AllScreens enumeration to get a reference to all the user's screens (assuming a multi-screen setup). I'm then using the following to set the forms:

In my home form I have a splitcontainer and few buttons. When the buttons are clicked respective forms are opened in the splitcontainer. The splitcontainer is anchored- top, left, right, bottom so that when the home form is resized the splitcontainer resizes itself automatically. The controls within the other forms are also anchored properly to resize themselves accordingly. But the problem is when i open a form in the splitcontainer, even if I resize the home form, the controls in the form within the splitcontainer aren't resizing. The reason is when the home form is resized the splitcontainer is resizing itself accordingly but the form inside the splitcontainer isn't (as forms don't have anchor or dock properties so I couldn't set them). As a result though the controls in the sub form are anchored to resize themselves yet they aren't.
View 1 RepliesWhat im trying to do, is have my program run full screen on the primary screen, and diable all other screens. I have it 'full screen' and constantly on top of everything with this
Dim b As Boolean = _
SetWindowPos( _
Me.Handle, _
[code]....
It is in a timer, so its always on top. how do i turn off, or disable all other monitors, besides the primary screen. (How do i check if they have other monitors, and if they do, how many, and disable them all, with exception to the primary screen.)
How can I zoom into monitor to see a pixelated image of the screens content?
View 2 RepliesI have a button that will run a video file in the Windows media player box, first up, is there a way for that video to display full screen on a secondary monitor?My plan was to have a large form that spread across the two screens with the control buttons on one side and the video on the other, is there an easier way to do this? Otherwise I think I might have to look at making an individual form for each screen and then somehow getting the buttons on say form1 to do the work on form2. Again is this hard to do?
View 2 RepliesNew to these forums but have been a lurker for a while. I searched through some "multiple monitors" threads but didn't find anything that fit my current issue, so I figured I'd pose it in a new thread. We have users with 4 monitor setups that are very particular about their screen settings. When we have to replace a PC for whatever reason, it is always a hassle getting their screen configurations the way they were prior to the switch. Is it possible to create a small VB app that will scan their current configuration, save a "settings" file, and re-apply the settings on the new PC? What I mean by configuration is screen resolution, setting the primary monitor, etc. Theoretically this sounds like it can be done, but I wanted some opinions on it.
View 1 RepliesNow this program will only be used on systems that I produce, and send out. I need to make sure that for any monitor that these people use it will always be at the standard resolution of 1440 x 900..
I have tried setting up profiles with catalyst control panel, but if you plug in a different monitor to the one that was plugged in when you made the profile it wont recognise the screen and the system wont run properly.
So I wanna see if I can change the resolutions of the screen that will be plugged in the monitor slot and also if possible make sure the other extended screen should there resolution of 1024 x 768..how much control can you get over the monitors that are plugged in?
I have created a security program that monitors the keystokeswebsitesprocesses... I want to FIRST ask if this is a legal question; for, my purpose in this program is security reasons (eg. following up on employees to make sure that they are doing what they are paid to do. They all know this is running, and have been warned not to go to sites and enter information they do not want reviewed).
Second, I want this program to be hidden so that techy persons cannot go into task manager and end the process, then go on to some porn site! How could I make this app hidden, or at the very least make it 'un-end-able' from the task manager?

View 1 RepliesI am using the MSChart object in VB2010. Live futures data is put into an array, then added one point at a time to a line chart (Chart1, one line only) using (1):
frmChart2.Chart1.Series("data").Points.AddXY(sec10, spreadarray(0, sec10))
All fine and good. However, by the time a few thousand data points have come through, its getting hard to see the detail in the chart, therefore I reset the x-axis so that I just see the last 200 (say) points, using (2):
Chart1.ChartAreas("ChartArea1").AxisX.Minimum = frmPrices.sec10 - CLng(lstChartpts.Text)
...where frmPrices.sec10 is the total number of data points, and CLng(lstChartpts.Text) is the number of points required. So if I have 1000 pts, and I wish to see 200 displayed, the AxisX minimum in this case is 1000 - 200 = 800. Points then start to build again one at a time. I am happy with this except that the Y-axis scaling is still taking into consideration all 1000 data values, so need to reset the Yaxis maximum and minimum. No problem (3):
Chart1.ChartAreas("ChartArea1").AxisY.Maximum = (max of the last 200 values + a small increment)
Chart1.ChartAreas("ChartArea1").AxisY.Minimum = (min of the last 200 values - a small increment)
The problem comes in when I want to change the number of points to display back to "ALL". I could re-write the code to use the max and min of all values, as in (3), but I'd rather just reset the yaxis back to the autoscaling that the chart started out with. I've looked everywhere for a property or method to do this! Or is there a way to autoscale the yaxis according to only the displayed values?
So, I coded a graphics engine for myself. I can make meshes, save them, load them, rotate them, position them, scale them, and light them. Unfortunately, when I scale objects to a size other than it's original size, my lighting intensity changes (seemingly proportionally) with the scale of the object! Ambient light still works correctly though. Any suggestions?
View 4 RepliesI'm using the following code to print an image from a PictureBox. All works great except for scaling images down if they are bigger than the print page. Is there a method I'm missing to do this?

I cant find how to scale the output to the printer. Currently the size of Form1 is set to A5 because that about the most the VDU can handle.When I send this to the printer from PrintForm1, naturally it prints at A5, ideally Id like to scale that up to A4 but cant find how to do it. It seems to me also that Id like to know that it was correctly centred to the paper.
View 1 RepliesI am attempting to write a routine that will accurately scale an image to the specified size while keeping the original aspect ratio of the source image.Most [if not all] of the images that the program will be working with will either be 4x3 or 3x4 ratio and normally will be output at 800x600 or 600x800The thing that has me stumped at the moment is what kind of formula I would need to use to resize at image that does not meet the 4x3 ratio. Something like say a 600x255 image or a 255x600 or some other oddball size.

View 5 RepliesI created an image-viewing control for my boss that incorporates panning, zooming via the mouse wheel, and drawing a box to zoom to. The control needs to support very large image files (i.e. several thousand pixels on each side).
It all works, but whenever the code is scaling the image the control UI becomes unresponsive. My boss had me use threading to set the scaling code apart from the UI. The scaling code is now definitely on a separate thread but the UI is still bogged down while scaling code is running!

View 2 RepliesImagine I have a rectangle say 400px x 300px. All of this is very easy using Sytem.Drawing. DrawImage. But then I want to leave the left hand side as 300px but change the right hand side to 250 px. I can draw the box using 4 DrawLines but I don't know how to squash the image into the new shape. I want the right hand side of the shape to be 250, the left size 300 and the top and bottom 400px.I can't use DrawImage as it expects the left and right sizes to be the same. Is there a way to manipulate the image into the new shape?I've looked at other questions, but they only apply where the left and right hand side is equal.Any thoughts on how to squash an image into a shape which did not have parallel sides?
View 3 RepliesI've checked through most of the nfo I can find in forums about scaling a picture, but still haven't stumbled over the answer. ALl I want to do is print my form on the printer. The problem is I don't know what monitor the form is being dispayed on and how big or small the user has madt it. I just want it to fit on the printer when it is printed. Basically I want it to, "Fit the Page".
I thought I could do it by using a rectangle and adjusting the size of the rectangle to fit the 8.5 x 11 paper, All this seems to do is magnify my form on the printed page and clips the sides and bottom of the form instead of making it "fit" on the page. What am I doing wrong?

I have a picturebox that has an image on it. The user will be able to draw rectangles on that image, and the rectangle will have a string drawn into it. Frankly, I have no idea about the shape or size of these rectangles except to say that they will have a "reasonable" size to them. What I am trying to figure out is how best to draw the string inside the rectangle. Obviously, the size of the string is determined by the font, and I can measure this size with MeasureString in the Paint event for the PB. The size of the string as drawn must be less than the size of the rectangle such that the string fits entirely within the rectangle.
The problem is that MeasureString takes a font so that the size of the string can be determined in that font. That seems to require that I create a new font object, measure the string in that font, check to see that it is less than the width of the rectangle (don't have to worry about the height), and if the string is too big, reduce the size of the font and try again. This seems to have the potential to create and destroy plenty of font objects for the sole purpose of checking sizes. Is there a better way? How about a method that figures the maximum font size that can be used to get a string of pixel length X? The second half of this problem is something I haven't even begun looking at yet, but somebody has probably got an answer that will save me some time, so I'll toss it out here:It is possible that my rectangles will be high and narrow, in which case few strings will fit horizontally in the rectangle, so I might as well draw them vertically. Is there an easy way to draw text vertically rather than horizontally?
I often use VBA to automate internet explorer and interact with web sites.I can find links on regular URLs I navigate to, fill in forms on them, etc.But I don't know what these types of windows are that come up or how to get a hold of them to click links on them or enter text in their forms if there is any. It comes up then grays out the screen it came from. It looks like its some java popup or something. I'm not interested in the site this is from, its just an example of one to show what I mean. I've been searching and looking but can't figure it out.
View 5 Replies[URL]its a free hoster, so you have to wait 10 seconds.First here's the steps to replicate, then I'll explain what the problem is:
(1) Create a System.Windows.Forms.UserControl and add a button to the bottom-right hand corner. Leave the button anchor as default (top-left). Add some more buttons dotted around so that you can see that they scale correctly.
(2) Add the UserControl to a form in the construtor, after the InitializeComponent call.
(3) Run the form.
(4) Increase the form font size some way (eg click a form button).
All the controls within the usercontrol scale perfectly but the usercontrol itself doesn't. It's width and height are increased by way too much. Look at the margin now between the button at the bottom-right hand corner and the usercontrol.To correct the problem, the usercontrol must be added before the InitializeComponent call.If it wasn't possible for me to add the usercontrol before InitializeComponent, is there any way for me to correct the scaling?
I am trying to write program in vb 2010 that is independent of screen resolution. I am designing the program in 1920*1080 and when I change the resolution to e.g. 800*600 everything blows up and the program won't fit the screen. I have tried three different approaches:
loop through all controls and scale their position and dimensions
Friend Sub ResizeControl(ByRef ctl As Control)
'---------------------------- GET SCALES -------------------------
Dim DesignScreenWidth As Integer = 1920
Dim DesignScreenHeight As Integer = 1080
[Code] .....
None of these methods has worked for me. One thing I figured out was that my main form is larger than 800*600 pixels so when I run the designer in 800*600 resolution VS cut down the with to 812px so my calculations of with and thus scaling ratio becomes wrong. This error goes applies for all three methods.
