I have created a program that opens and closes web browser controls many times. I need a way to release as much memory as I can but it's difficult as even calling the dispose method doesn't seem to work. Do I need to do anything else to the web browser control to fully release it's resources?

View 5 RepliesI'm working with datatable with a big amount of data. On the way of converting the data to the final form I need I would like to get rid of the datatables that I don't need anymore. This is mainly because I have three really big datatable that pumps up the programs memory usage close to the limit. (Out of Memory Exception).So is there any way for releasing this memory used by the datatable that I don't need anymore?
View 9 RepliesI have a little problem with my program, Boot Animation Previewer.Firstly, it loads the .zip file and extracts the boot animation in a folder called Temp. If there are existing files in the Temp folder it deletes them. But, once the boot animation is previewed, you can't select another boot animation, until you restart the application, because it gives an error, saying that the program can't delete the images, because the process is using them

My question is: how to stop using the images? I've tried to dispose the form that loads the .zip file, but with no success.
I'm trying to make sure that I don't leave any loose ends open in my application and am concerned about a few but might get my answer from this one. I've "overriden" some functions so that way I can try and keep all the resources as clean and free as possible. So in this instance, I have a function called ExecuteReader which returns a DbDataReader as normal, but all I had to pass to it was a SQL string rather than recreating a DbCommand every time. I want to make sure that even though I'm unable to call dbCommand.Dispose() that it is actually doing so.
[code...]
In here, I set the _dbReader to what I'd get from the function and eventually I close the _dbReader. I do not close the connection as I don't open it each time I make a query. This is a SQLite database that only one user will be using at a time (small application with very very very little likeliness it will grow) so I didn't think it necessary to close and open the connection all the time. Maybe I'm wrong, not sure. Using it this way though, it is potentially ok for cleaning resources?

Is there a good web browser component for VB.NET that has all the features of the regular one? This includes printing and progress bar support. I've tried WebKit.NET, but it didn't have progress bar support. I also tried xlurunner but it had no printing support. Is there another web browser component that has both printing support and progressbar support? I shouldn't have to omit features from my browser just to get a better rendering engine.

I coded a web browser over the course of a year called Nova - very advanced with tabbed browsing, bookmarks, homepage, history, etc etc etc etc. I could go on all day about how advanced it is. But.. there is one flaw. You cannot make it the default browser; I don't know the code!I already know the CommandLineArgs stuff so it actually opens the HTML file rather than just opening the program; in fact, I already can make files open with Nova completely. It's just the other stuff - you know, when a website is to be opened from a help file or something, it opens with Nova, Windows recognises it as the default browser, stuff like that.
View 3 RepliesOther topics around the Internet are all unfinished topics, so I'll ask this myself. How do I set a self-made browser as the default browser? I know it has something to do with accessing the registry and checking what the value is in some places, but I'm not quite sure. Now, I've made this browser called Nova;
very well coded and advanced, tabbed browsing, bookmarks, homepage, history, can change default search provider, uses Gecko as its engine so it's not just an IE shell, etc. It's been developed over the past year and will still continue to be developed. I'm almost ready to release the first version - but I just need this annoyance solved.

last question how do i go about making new windows not just for browser windows but, making something like firefoxes options window.. not necisarily to do that but just to make i guess another form pop up...
But now I have a need to allow the user to choose a folder path without selecting a file. Basically a folder location, on the local hard drive where my code will read the files located in the choosen folder and process against them.
I am drawing a total blank and my web searches are not giving me what I am looking for.
I initially developed this with a Windows FolderDialogBrowser control, but it will not run on the web server, likely a security issue, and I can not change it.

Ideally I just want to zip up the minimal amount of files and for people to put this in a folder of their choice and just run it.

Within that folder are the necessary files (a DLL and a .EXE) to run my application. Can I just supply those two files out to people?

Currently we are using the Microsoft data access library Writen with a Oracle data provider for the framework 1.1. My customer has mandated that we upgrade from Oracle 10G to 11G release 2. 11G requires the .net framework 2.0 Is there a way to use the new Oracle data provider 11g release 2 with the older frame work. I have looked at/attempted changing the policy for oracle in the Windows assembly but my understanding is because its a third party DLL, I cannot.
View 4 Repliesin main form, when a button is clicked, it opens a new form which has a webbrowser. users can use it to browser some sites. if the user closed this form, it goes back to the main form. and they can click button to open the browser form again.
I noticed that one thing. if the browser form is opened, it uses much memory (which is normal because of the site it browses). however, after the browser form is closed, the memory is not released.
In the browser form, when it is closing, the webbrowser is disposed and dereferenced. and no other part uses much memory in the form. GC is called too. what else should I do to release all memory the browser form uses?
now, it is like once the browser form is opened once, the memory usage never goes down even the form is closed.
