View 5 RepliesI 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 4 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?

View 7 RepliesI am creating a webbrowser with Visual Basic, and I have finished everything but this: When I click on an external link, (I.E. On a photo, or on youtube) it opens up in a new IE window. I want it to open in my browser, not Internet Explorer.I have read everything I have found on this subject, but it is all for normal web browsers. I want to do this for a tabbed web browser, not one without tabs. Basicly, I want to use this code with my tabbed web browser that uses tab control.

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.

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.

View 4 RepliesWhat is the 'proper way' of giving my application to people?
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.
I've noticed from playing with a "Publish" I end up with a "setup.exe" and also a "Application Files" folder.
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.

On the back of a Windows Form, I get a window DC, create a Graphics object with Graphics.FromHdc, and then dispose the Graphics object before releasing the DC.
Private Declare Function GetWindowDC Lib "user32.dll" (ByVal hwnd As IntPtr) As IntPtr
Private Declare Function ReleaseDC Lib "user32.dll" (ByVal hwnd As IntPtr, ByVal hdc As IntPtr) As Integer
Dim hdc As IntPtr = GetWindowDC(Me.Handle)

Why did they do it this way?Should the DC be released before or after Graphics.Dispose?It is possible that the wrong order can cause resource leaks or memory corruption?

View 2 RepliesI have a main window in my project, and numerous other child widows inside the main.I have noticed that. When I open the main window occupies 1500K of memory, when open one child window then adds in occupied memory 6000K.When I open the second window doing the same. When I close the two child windows the occupied memory is not released.So What I want is to release the occupied memory when ever I close child windows.How I can do that? with some code example in vb.net if it is possible.This problem often sawing in the computers on the Local NET not in my computer (developer computer which has the SQL server on it).
View 7 RepliesI made a .exe file of my project (in vb2008 express ed.) and it was all working and then I copied the release file out of my project and an error came up (something about UNC share) and i realized the path was wrong, so when I tried to delete the Release file (currently on my desktop) a pop up message says you need to be administrator to delete this file so I press continue (as I am the administrator) and another message comes up saying "You need permission to do this" "Try Again?", when I click "Try Again" the same message comes up. I know this isn't directly involved with VB, which leads me to my second issue:
How can I create a file that is external from VB yet it still works? In my code there is a path that connects it to SQL is it perhaps something to do with that?
