I'm making a photo editor and the size of the image depends on the size of the window, like the Zoom mode in the BackgroundImageLayout property of a form. It works sometimes: when resized only a small amount, it does nothing, but when the image is resized more than that, it jumps to the right position.
vb.net
Private Function GetImageRect() As Rectangle
Dim r As New Rectangle()
If Me.ClientSize.Width > Me.ClientSize.Height Then
i have loaded an image to picturebox from resource which can be any size,but i just want that a image i have loaded to my picturebox,image resolution is 48*48,than now how i can set image size in picturebox.
I am trying to resize a form1's background image and make its "BackgroundImageLayout = ImageLayout.Center" from form2 but it keeps disappearing of the screen as it resizes.
Private Sub btnResize_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResize.Click Dim nNewWidth As Double = 0 nNewWidth = Double.Parse(Me.Label5.Text) / 100
i have found the Hwnd for a window and i now wish to get information about this window, the location on the screen of the window and its width and height. Problem is the values i get are not anything near right.
vb.Net <DllImport("User32.dll")> _ Private Shared Function GetWindowRect(ByVal hWnd As IntPtr, ByRef lpRect As Rect) As Boolean
[Code].....
this returns 0 for height and width and the remaining figures are nearly 0 (1.68E-311) what am i missing and how can i get this information?
Am trying to match characters or combination of the characters i specify in any order they appears
vb Regex.IsMatch(teststring "[nuls]")
what i want matched is either any single character, or combination of any of them in any oder. this means that it should not match any character not specified in the pattern.
I am writting a program that aims at filling up bookmarks of a template with data retrieved from a sql server db. The form opens a Word document but I can't control the position and dimensions of the word document. It seems that I can't manage to overwrite MS Word default settings for position and dimensions. I want to be able to display the word document close to the form.Here is the code that I have tried and doesn't work:
I'm reading in an image (jpg) using the code below and I need to check that the image is no bigger than 150 pixels by 150 pixels and is less than 25k, how should I do this?
the user will pick an image on their hardrive and i will put it on a pdf file using itextsharp with vb.net. how do i manually set the dimensions of the picture?
I'm reading a folder to assess the width x height of jpeg's, to classify them in various ways. Opening each as a bitmap and reading the bitmap width and height works but of course is laborious and very slow .... I've read various JPEG file format papers but retrieving the image pixel width and height seems none too obvious. Is there a logical way in VB to get this info quickly? My jpeg's are bog-standard ones made using VB's "Bmap.Save(Fname, ImageFormat.Jpeg)".
How can I crop an Image to preset dimensions and size using code.I can do this with MS Office Picture Manager, but I want my users to do this from within the app. using the preset dimentiomns and sizes.[URL]
I need a code that will load text, the correct image to match it and the command for each image. what i want to do is make a program that will download a swf and an image into to folders. then at startup the program will load all the swf and images and put the images into a listview so when you click on the image for the swf file it will give the link to the swf so it can be loaded.
Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.
I'm upgrading my VB6 project to VB.NET and I found one of the problem below relating to dimensional array.Here's my VB6 coding :
Private Function ConvertMatrixToBase0(ByVal MyMat() As Double) As Double() Dim i, j As Long Dim ConvMat() As Double[code.]...
When i port it over to VB.NET, i encountered error message 'ReDim' cannot change the number of dimensions of an array. for the line highlighted in red. And I suspect that VB.NET need to always define the exact dimension of the array during the declaration. But for the function above, for the array of 'MyMat()', I do not know what is the exact dimension every time it runs, and that is why i need to check the dimension of the array.My question is do we have any solution in dealing unknown dimension array in VB.NET? As in VB6, we can just define Array() instead of Array (,) in VB.NET.
if you guys have used office 2003 or better( i am sure all) then you would have seen that when the help window open it causes the active windows say of MS WORD to change accordingly so that this help windows fits with it along the right side and this functionality i want to implement in my VB windows application and have no idea how to do it Also i have seen this feature in GOOGLE DESKTOP GADGETS...
i want to implement that when my application opens which ever is the active window( of any application) snaps to the left and allows my application to fir in the right hand side i am developing my application in VS 2005 using Visual Basic.
Can I make my toolstrip backcolor match my window frames color automatically? Since frames are controlled by themes, can I set the toolstrip color in the IDE using the System tab and selecting one of the options, say Inactive Border color?
For example, if my theme uses a blue frame color, can I tell the toolstrip backcolor to match it somehow?
How can I resize a window? I've done it by using GetProcessName and MoveWindow, but with MoveWindow it doesn't work on different operating systems/computers. what would be an alternative?
How would I re-size the window @ a point relative to its parent location and size. I am using code from Make an unowned window's parent to my form, to be able to set a windows parent to panel1.
Dim proc As Process ' Start the process proc = Process.Start("C:UsersDmitryAppDataRoamingSpotifyspotify.exe") proc.WaitForInputIdle() Dim tmp_hWnd As IntPtr [Code] .....
This works on most windows except for ones that are customized. Maximizing the window will maximize the window to bounds of the actual screen bounds instead of the panel1 bounds. Code works fine with normal windows but not with this one. (Spotify Window.) SendMessage(proc.MainWindowHandle, 274, 61488, 0)
I am writing a program that is navigated manly by using tabs, the tab panels (If that is what they are called) hold the vast majority of the GUI, only leaving space for the menue bar and a few rarely used window forms. So my question is this, what do I need to do/set to make the tab control (Or tab Panels) re-size with the window it is in when the user re-sizes the window?
I have an application that while running (it doesn't have to have focus, it can be minimized or another window can have focus) can listen and respond to global hot keys pressed. For instance I have the key combo Ctrl+Shift+0. When this hot key is pressed my app can recognize this and then I can do something.
This "something" that I want to do is:
1. Know what window is currently active and has focus when the hot key was pressed. And...
2. Change the size of said window
I can currently identify what window has focus by the following (the code block is inside the function that fires when the hot key is pressed):
Code:
Private Declare Function GetForegroundWindow Lib "user32.dll" () As IntPtr Private Declare Function GetWindowThreadProcessId Lib "user32.dll" (ByValhwnd As IntPtr, ByRef lpdwProcessID As Integer) As Integer
[Code]....
I can get the handle to the active window and the process that owns that window.
Having this information, how can I get access to the window itself? Furthermore, get access to it's properties so I can change the size of this thing? I'm not sure If this is the right information to be gathering for what I'm trying to accomplish but it seems that I'm close.
I have a form which has no window borders, but I still want to be able to resize the window? How might i achieve this? Even just a few options, like 'small' 'medium' and 'large' size would be fine if it cant be normally resized.
Is there any way in c# or VB to automatically move the controls in a panel when the window is resized. I do not want the Anchor property, which only resizes the control. THe use is that controls are added at runtime to the form, and when the locations/values are loaded on a computer with a larger monitor, they are in the incorrect positions.
I came across an issue which I see has been discussed a few times, but there doesn't seem to be a defintive answer to the question.How can the child windows in Silverlight 4 be dynamically sized to fit within the size of the current browser window?The problem is on smaller displays where the browser window may be smaller than what the child window was originally developed for.What occurs is the OK and Cancel buttons are off the screen and cannot be scrolled to via the browser.You can duplicate this problem by simply shrinking the height of a browser window manually while the child window is displayed.The controls will disappear and there is no way to get to them.This is pretty much simulates what users with smaller monitors see.So the question is how can you set up a child window to dynamically size itself so it users can still interact with it?
ok when my program is running from scratch I have a piece of code that just says if the size is this.. then make this.. else make this.. so it just makes is small and big..after you close it.. it hides itself in the sys tray... if you bring back out of the system tray.. and click the button to make small or big.. does nothing.. it come out of the sys tray as the large size.. and wont go small again..
does something on the form get set when you hide it ? that needs to be unset to let it resize it ?
I had been looking for a way to move and resize an external window from my application and I came across this method: [Code] now this does not work, after looking around I many threads about how api calls in .net are different.
I can only manage to code browse for folder, I need to browse for file though. [code] My second problem is how to make the form resize when the window is resized? What I mean is if the user resizes the program from looking vertical, to looking horizontal, that the form resizes with it and some parts don't just disappear.
