View 1 Repliesif i webbrowser1.navigate "[URL]" when this page was loaded then automatically navigate to [URL] i try webbrowser document completed event but still not working
View 4 RepliesI have a few subs that run under Webbrowser1.document completed section of my app I know the code words because I tried it out using a new project and tied the code to a button and it works great. After stepping into my code during run time it appears that the app is trying to call my sub before the next page appears. What would be the way to place a pause on the Thread so that the web page can catch up before running the next sub?

View 4 RepliesI'm a novice in Visual Basic and I'm currently experimenting with development of a small application that includes webbrowser control. When I tested the browser (actually tested a few of them, not developed by myself) accessing websites using flash content, it always returns message "Flash not installed" and prompts me toh have it installed. I remember IE6 used to have problems of this kind.IE7, FF and other browsers work just fine and detect flash plugin straight away.This is probably a known issue, but I just couldn't find anything on it in these forums.
View 3 RepliesI have a application using Webbrowser Control, I want to detect the click events for anchors in web page. I dont need code, just the directions to look into.
Edit
I didn't find any solution for the problem but found a hack in Control.ModifierKeys, this works until now!
My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]

View 8 RepliesI've been asked by management to convert all of my applications from VB 2005 to VB 2008 (in preparation for taking them to VB 2010). I have a VS 2005 application that uses an ADO Data adapter which was defined using the GUI. I normally define my connections in code, but have been asked to get away from that in favor of ADO (and similar) data adapters.When I run the conversion wizard in VS 2008, it appears to convert this program, with some warnings and I get the 'Conversion Completed' dialog box. However, the VS 2008, will not let me close the dialog box, even after waiting for 3 hours. The only way to get out is to reboot the system.
View 6 RepliesMy form contains lots and lots regular expression and other things in one button. whch when pressed takes some time to process.. so the form kind of gets stucked while the processing is bieng done.is there any coding for which it diables the entire form until the process is completed? like disabling the entire form and showing a text "please wait ... processing data" so user can not use other buttons or features at the same time or it might get crashed.

For Each item In listVideos.Items

However this makes the program want to convert all videos at the same time... is there anyway to get the program to convert one video and then after the conversion code is completed to move to the next one?Should also be noted that I am using FFMPEG for this project.
how to detect when the "DEL" key has been pressed in a VB 2008 windows form?
View 5 RepliesI need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I need to know a way to detect if the mouse has been clicked anywhere on the screen. So as long the program I am making is open when the user clicks my program needs to do something. Please let me know as soon as possible if this is possible and how you do it.
View 5 RepliesI have a program that parses INI files (yes yes, I know, but I'm stuck with using them, not my own request), and it downloads external images (if the INI contains the path) to the program and cache's them.
Recently, I've run into a snag with the system. Most of the images use Imageshack for storage, but one of them has suddenly 404'd, and whenever I set it to the picturebox to the downloaded image, I get an out of memory error rather quickly (and the file itself is 1kb).
I guess I need to implement a checking system offline to find out if the image is actually an image or just a '404' text...but is there a way to not have to implement this clientside, and have it be checked when I download it?

View 4 RepliesI've come across involving a PictureBox.I am trying to create a quick Paint-like application, but I want something to happen in it. I want it so that when you draw or have drawn in a certain area of the PictureBox, you trigger events to happen (but they must only trigger once. This doesn't mean only one event can happen, it's just that each event can only happen once). How would this be possible to implement in my code I have now?[code]
