I am working on a project that somehow uses the web request technique. But I'm facing a tough problem, my application is a web scrapping application. The website I'm scrapping has a combo box list and which of course fires a do post back on change. I want to use the web request to raise or fire the event of the do post back with the value I want and extract the web source page. is that possible?
View 9 RepliesI am trying to extract some data from the webpage's element. Since it is based on the input I type in, the length of the output is different for every different input.
CODE:
I want what ever word/phrase of any length that is between "0.6em;">" and "</div>" earlier methods I've used for inputs was WebBrowser1.Document.GetElementById("Text").SetAttribute("value", TextBox1.Text)
I was wondering if there is something as simple for extracting the output.
anyone know any good tutorials for screen scrapping? what im trying to do is make an application where i enter in keywords ...
View 2 Repliesis it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?
View 11 RepliesI am new to working with SQL databases (and databases in general) so I do not have a lot of experience with how queries work and how I can practice them. When I was first learning xml and XPath, I found XPath Visualizer incredibly helpful after someone on stack overflow mentioned it to me.Due to this, I am wondering if a similar tool exists for SQL databases?Basically a tool that will allow me to connect to a database,enter queries and see somehow what the results would be like.
I have looked online a bit, however I have found relatively few options in terms of any utility that would do what I want, and that looks reliable.I will ultimately be writing an application to interact with an SQL 2008 server in vb.net, however for now I am just experimenting so I will know what I am doing when I actually want to create my application.So far I have managed to connect to the database using an OLE DB connection, but I am now looking for a way to experiement with queries without just querying and figuring out a way to interpret the results in my program. Basically I want to be able to remove the programming aspect of things so I can experiment with queries without needing to question anything in my code that is unrelated to the specific query.
Is it possible to change the application version without publishing the application? Because I'm going to make an auto updater which needs some version information to work, but I don't want to have an installer.

View 4 RepliesWithin my application we store objects i.e images,word docs, etc etc. These are stored in a listview and when the user double clicks the item it launches the default application assigned to the file type i.e a bmp will launch paint, doc will launch word etc etc.
Everything works great in all versions of windows except the new Windows 7 where i am getting this error message:
Im guessing this is something to do with permissions etc, but can anybody shed more light on this and where to look?
We are rewriting our VB6 application in VB.NET 2008. The application contains several VB.NET dlls and one COM OCX control.We want to keep our executable file in shared folder of Server and want to create a shortcut in all other PCs. (This is the way we deployed our VB6 application)We know that using .NET Code security option we can give permission for sharing exe of a VB.NET 2008 program and .NET Framework is necessary to install in Client and Server PCs.
1.In which place we need to change .NET Code security: Server or Client?
2.Our application has a COM OCX control. Will it affect our sharing?
3.Which resource will be used for running application: Server or Client?
4. We want to use local resource of client such as reading registry setting, INI file etc. Is it possible?
5.Where to put DLLs of the application: Server or Client?

View 2 RepliesWe are currently running a 32-bit VB.NET 2005 application with a 32-bit SQL 2000 data store. The network guru is going to be upgrading the server and SQL to a 64-bit version on both. Will the 32-bit application still connect to the 64-bit data files? I am guessing I will somehow need to tie in the 64-bit drivers somehow, but will those work on a 32-bit development system?
View 4 RepliesI have developed an application in Visual Basic 2008. I really love the product.I am 99% done but am hung up on a Publish issue.I know the Publish feature is not a full install program - but it handles downloading the application prerequisits so well I really want to use it.My problem is the Install path. It installs my application is the strrangest drectory appdatalocal 615252-191891-919 (goes on for ever)
I can set the install directory to something simpler. Would love to get it in Program Files but will settle for AppData if it can be a reasonable directory name. If I have to tell a customer to look in that directory for some reason I would have to read off about 60-70 alpha numeric characters for the directory path - that isn't feasable.

View 3 RepliesI downloaded an itextsharp DLL that I would like to use in my vb.net 2008 express application.In which folder should it be placed?I went into choose items in the toolbox and tried to add it but I got an error

I am writing my first application in Visual Basic Express 2008 and the program conistently hangs (Not responding in the Task Manager) midway through execution. The operating system is Windows XP Professional SP3 running on a 1.20 GHz Intel Core Duo CPU with 2 GB of RAM.
The application has very deep layers of subroutines and functions, all of which are using lots of math routines. There are no recursive routines anywhere in the program. The program creates and destroys quite a few class elements, and I have written dispose methods for all of them using IDisposable, setting all the properties to Nothing. I also use GC.Collect() to force garbide collection, and GC.WaitForPendingFinalizers(). As a result, I don't think there are any memory leaks.
I think the depth of sub and function calls are causing a stack overflow, but I'm not certain. I have tried without success to increase the stack allocation to 2 Mb using Editbin.exe after reading some forums, but nothing changed. I then searched my machine and did not find EDITBIN.EXE.When the program hangs up, the background of the forms on the screen turn to solid white and the controls are no longer visible.It looks like a window pops up but it disappears too quickly to read anything. If I view the task manager while the application is running it hangs immediately. I have not published it, I am still developing and running it out of the VB environment.The more complexity (sub and function calls) I add, the earlier the program hangs.

So heres a image of what I'm trying to do [URL].. My application is a toolbar sort of thing.. I want it to be stuck to the user's taskbar and the '::'s in the example will be draggable areas so they can move the toolbar left and right above the taskbar.
What I need help doing is: 1. How can I get my app to stick to the users taskbar? I know I cant set the position to mine because different screen resolutions etc, is it possible to do?
2. How can I make the draggable areas only drag left and right and not up and down?

My application was built with VB.NET application. It's EXE application. It's already running well on dozens of Windows host (as independent app - without development env). Now I try to run it on Windows 2008 server (as independent app), but the form does not displayed. Nothing is displayed. When I debug, I see that it's running all "form_load" subroutine, but then nothing is displayed. It works fine on many other Windows machine. What can be the reason? What should I check?
