I made this VB.NET code to take a picture of my entire screen, but instead it only takes a photo of the focused area. Why is this?
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("{PRTSC}")[code]....
I have tried to control another application to automate a process we do 100 times a day. It is simple enough, a few key strokes is all but I have been foiled in all attempts
View 1 RepliesCurrently 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.
I need to take a snapshot of a form which is not necessarily visible on the screen. I need to save that into a Bitmap object. I cannot use Graphics.CopyFromScreen() because if there was anything obstructing the form, it will appear in the snapshot taken.
View 6 RepliesWhat is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.
View 3 RepliesPrivate Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
CheckBox1.Checked = True
While CheckBox1.Checked = True
SendKeys("{END}")
End While
End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."
I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).

Looking for some code to upload a photo to facebook using the Graph API in VB.NET. I have the Facebook C# SDK, but it doesn't support uploading photos as far as I can tell.Accessing the photos works fine and I can send other content to Facebook fine as well. Just not photos.The facebook documentation talks about attaching the file as a form-multipart request, but I have no idea how to do that. To say that its not very well documented is to put it lightly. Even the guys I hire to do this kind of thing couldn't get it to work.I've found this: Upload Photo To Album with Facebook's Graph API, but it only describes how to do it in PHP.I've also seen varying method from different sites about passing the URL of the photo as a part of the HTTP request, but after trying local or remote URLs several times I kept getting a bad url error or something like that.

View 2 RepliesI'm trying to do for a website. I've got a header banner that is 900px wide, and I want to display 4 random images across the banner. (I've got about 20 photos at this point, and I want the header to select from them.) I can get the code for the random selection, but what I'm looking for is a way to blend about 10 pixels near the overlap. If I have each picture exactly 225px wide, I get a "hard" line between the images. I'd like to make the images a little bit wider and soften the edge by overlapping and blending the images together. I have figured out how to get the image back to the web browser, but I don't even know where to start on trying to figure out the blending. Graphics really aren't my thing.
View 2 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'm making a program that will print jpeg's.The way i have it is I have lots of forms with buttons and when you click a button it prints the photo and a databound label with a line of text.The problem is that i want the user to be able to click one and then click another button right after, to print another one, but as soon as i click one, the program freezes until the photo starts printing so the user cant click to print another one right away.Each picture is around 4 mb.Is there away to make it go faster?The pictures i'm printing are from a pdf file with text and images in it that were converted to jpg. Each page is another jpg. Is it possible to print directly from the pdf and would it be faster since the words are 'text' and not a 'photo'?

View 1 RepliesI've almost finished my multimedia project. On the photobrowser (which constructs thumbnails of every photo in a folder and draws them onto a bitmap which I then make persistent and from which the user can select a thumbnail and the image is shown in full on a new form). You can print the bitmap consisting of 100s of thumbnails or the full image associated with a thumbnail. The onloy thing missing is getting all the Exif info - which is proving more difficult than I expected despite the propetyitems in vb.net. Yes, I have set the encoding to UTF8 etc.
