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. How to solve it.In short I want the form in the splitcontainer and all the controls in it to resize automatically when the home form/splitcontainer is resized.

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.
I converted a VB6 application to VB.Net and in doing so, I seem to have lost the ability to auto-align the controls on the form. I thought I could change that in the "Tools > Options > Windows Forms Designer > General" area but that doesn't seem to work. Anyone have any ideas? I really don't need to use a grid for aligning since the auto-align functionality can be used but I just don't know how to get it back.
I have a project running in my old computer. It has panels,textboxes,labels etc. It occupies the full screen when running.I bought a new computer with a widescreen format. When I run this project it only occupies 2/3 of the screen.
What properties of the controls must I use so that I can run this program in any size computer and still occupy the full screen i.e the size is proportionately resized depending on screen size.
I have a form containes some controls (buttons) how i can make the program auto-scan these controls one by one automatically and whenever the mouse on a button the button select for a time and I can press the enter key to click this button otherwise the mouse will go to the next button and so on.
been trying to find examples of how to go about auto sizing the controls i have within a grid control if the users screen is larger than the default size.Currently i am unable to resize the controls when i enlarge the form. Is there any code currently that can find all controls inside the grid and resize them on the fly when the form is resized?My current code is:
How can I add controls to a form in code and set the properties of the controls using the With statement?Also I would like to know how to add a container control and then add a control to that container.
I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
I 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):
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):
...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?
I'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?
Screenshot, large image outside of the paper bounds:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click AddHandler PrintDocument1.PrintPage, AddressOf OnPrintPage
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.
I 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.
I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.
Here is the code that calls the sub form.
Code:
where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.
Here is the code in the sub form.
Code:
Now, I need to refresh this sub form every -- minutes, depending on how the user wants it to be. For this I have given a NumericUpDown control to select the mins. All this works fine. But how do I refresh the dataset and the datagridview?
I have a module level sub that I use to clear text fields etc on my forms:
CODE:
The problem I have is in the last few lines of code as I'm not really sure how to access the text boxes contained within the tab controls (of which there are many tabs and many text boxes).
This is the closest I've got but I am getting an "option strict on disallows late binding" error on the tabCtl in the following line.
I 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!
Imagine 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?
I'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?
Here is what I am using: Public MyForm As New Bitmap(Me.Width, Me.Height) Private Sub ToolStripButton3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton3.Click
Im currently in the mid of making a drawing project , and part of it is free drawing using Graphicspath object
now drawing is ok,moving or dragging the drawn path is done using System.Drawing.Drawing2D.Matrix but the problem is using System.Drawing.Drawing2D.Matrix object to scale the graphicspath object results into scaling and moving the drawn graphicspath on the same time ..
any resizing method code is listed below
Public Overrides Sub ResizeShape() Dim Sqrt As RectangleF = GetBounds() Dim Dx As Integer = MoveResizeEnd.X - MoveResizeBegin.X
I have a axwindowsmediaplayer object in my form which plays a video on load, but unfortunately the video seems too small and there is a massive black border around the video, is there anyway I can stretch the video to fill the whole player window?
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?
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?
[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?
