I have an application which is supposed to convert a video via DirectShowSource.I have a checkbox which enables a button called "btnviewcrop" which shows a new form called crp.vb for cropping/shearing pixels off the video.
Now, I have a Panel1 that I want to set as the owner (the video drawing surface) but when I set it to open, the application crashes (Error: Object reference not set to an instance of an object.) and I do not understand how to fix it.

But I cannot do it... Does the printpreview work with only Word Documents(.doc), Can I use a TextDocument (.txt)
PrintPreviewDialog1.Document = OrderReport.txt
PrintPreviewDialog1.ShowDialog()
this is my first time making an application so I would like to make a Login form in VB. I haven't gotten into any problems so far but my question to you are the following1) Is it possible for me to make an event/action that will allow it to work with the script that is php? IE: Application has a button that will scan all files in /public_html for viruses, when the button is clicked, it will send the event to cPanel and make it scan all files.2) Once the user has connected and all information has been verified make another window show and the new application will be the new window.Another question I have isRight now I'm using WHMCS(url..) for my billing system they have an intergtation code that I use for my web page and it goes like this

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

View 14 RepliesI have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

View 2 RepliesI 've been searching for quite a while to find a way to preview ANY type of file (not just images) much like the Windows XP Explorer does. Eventually I found a solution, using the WebVW.dll (which I had to import to .NET by using AxImp.exe - more info here). This, actually worked like a charm.
However, recently I upgraded to Windows 7, that, in all their greatness, spoiled my hard-earned solution
It seems that WebVW.dll doesn't ship with W7, and even more, it won't register even if you find it, so my solution cannot be deployed.Does anyone have any idea how to go about this?

Offset 12: Store Width of BMP (Short Integer) Offset 14: Store Height of BMP (Short Integer) Offset 21: Store Size of BMP File in bytes format (Short Integer) Offset 28: Store BMP Byte (Without Header of BMP) I Store that information into Datagridview...I already successfully to extract the image by creating the Header then write the bmp Byte into offset 54 (offset 0 - 53 is header of bmp file), Here my code to extract the BMP:

The Print Preview document is set to the print document.[code]...
When I print the document (from print preview or my print button) the papersize/margins are different...this is how:
1. If I draw a rectangle from (0,0) to some width or height the point is in the corner of the print preview but on my actual printed page it is about 1/4 in to the right and 1/8 in down.
2. I have an extra inch or so on the right side and bottom of the "page" that print preview will print to but will be cut off in actual printing.
I am assuming that there are some default settings (like the printer gutter and letter paper size) that print is getting from the printer that print preview is not, possibly. I need to have my print preview look exactly like my actual printed page.

View 4 RepliesI am trying to get this code to re-size(by a percent) the pdf thumbnail it outputs(which needs to be initially scaled down to 15% of the size of the original pdf document size).Currently, the code only adds the two dimensions as pixels, then renders the image, and draws it into a PictureBox.The code uses Ghostscript as you can see. The problem I am having is getting the dimensions of the PDF file. How can this be done? The code will be posted below:

View 1 RepliesI have 2 forms, 1 is for control and the other is for display. Its 2 because the 1 for display will consume the whole screen and there's no space for buttons.Im trying to control form4 using form2 or some other form, navigating a certain webpage in the process.
I have this code for the control: but it does not work, what would I do?[URL]..
This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":
Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)
[Code]....
In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.
I know there are several ways to publish updates but I would like to know the best way to do it. What I already have configured is a shard network folder which I intend to have the program update from there. What would the best way to publish updates to the folder be?
