Re: Associating Files to a particular exe..

5-Sep-06 20:22

Hi,
There are several ways to associate a file with a particular program. In Windows XP the easiest way is to right click on the file and select Open With -> Choose Program. Select the exe file that you want to open the file with and then click OK (don't forget to select the "Always use the selected program to open this kind of file" checkbox). The operating system associates the file extension with your program and the next time you double click on a file it opens it with your program.
Hope it helps.

Hello

This depends on wither the Application is yours or not. If it is your application do this:

1- In your setup:
a- Right Click on your setup project's name => View => File Types
b- Right Click on "File Types on Target Machine" => Add File Type

2- If you want to associate the filetype with another application that's not yours ignore this step. In your application, use Enironment.GetCommandLineArgs() to get the filename

If you want to make an application like a "Filetype associations editor". Edit the registry with it. In the registry, any file extension has a key to associate it with different applications that appear in the Open with... list if there are more than one application associated, and make one of them as default. For example, search your registry using RegEdit for "jpg". It will return all keys including associations with jpg files. Understand the structure and make your application editing all keys with the changes of the extension name. Shouldn't be too hard.

problem on capturing the browser close event

gtechrohit5-Sep-06 19:51

need to capture the browser close event( when user clicks the 'X' button on top right) to confirm from the user if he wants to save the data on current page. I am able to capture the event by window.obeforeunload = ConfirmOnClose(this is name of function). Now when the user clicks on "Yes" to save the data, i use the method __doPostBack to call the server method to save my information. The problem i am faced with now is that a Default Message Box of window also prompts up to ask the user
"Are you sure you want to navigate away from the page.

Press Ok to continue or Cancel to stay on the current page."

This message box is not needed and i want to supress it.

I have tried to do window.opener='', but that also doesnot help.
I am using Asp.net 2.0 environment.

I need it very urgent. All suggestions will be highly appreciated.

i am pasting the code for reference:

function ConfirmOnClose()
{
if(window.event.clientY < 0 && window.event.clientY < -80)
{
if(Page_ClientValidate())
{
var result = confirm("Do you want to save the data in the form?")
if(result)
{
__doPostBack('ibtn');
}
}
}
}

Hi,
Inside a picture box (from what i know) you can't position the image. You can try to use the SizeMode property to set it to Stretch, Center, Normal or AutoSize.
Hope it helps.

The executables created by C# compiler and IL Assembler run on every machine. If your .EXE does not run on another machine, check the version of the local .NET framework.

Go to build and then publish. Then you recive an .exe file to install the program you made on other computers.

Re: .mp3 in to Byte Stream

5-Sep-06 20:31

Hi,
To convert an mp3 file to byte stream try using this code:

<br />
FileStream fstream = File.Open("example.mp3");<br />
byte []buffer = new byte[fstream.Length];<br />
fstream.Read(buffer,0,buffer.Length);<br />
fstream.Close();<br />

Then use the buffer to send data on the network. To recreate the mp3 file (in the receiver application) you can do something like:

<br />
FileStream fstream = File.Create("path\\example.mp3");<br />
fstream.Read(buffer,0,buffer.Length);<br />
fstream.Flush();<br />
fstream.Close();<br />

Adding a search to a toolstrip

6-Sep-06 19:50

Hi,
I had a look over the code i wrote and i must apologise because i made a mistake. When you create the mp3 file from a byte array the method that must be called is fstream.Write(buffer,0,buffer.Length) not fstream.Read(...).
Sorry. I haven't seen than when i wrote the code. Hope it helps you in your task.

I saw a video at one point where the author added a search to a toolbar using the Windows Forms designer, but I don't remember where I saw it. Anyways, does anyone know a way to add a database search to the toolbar through the designer? The video author had a dataset (and all the other controls, binding navigator, binding source, and table adapter) all setup on the designer.

Any help is much appreciated. Thanks!

Re: Advanced file properties

Hello

The concept of skins differs from an application to another. Some developers define skins in the applications as simply applying different colors to their froms. This is done simply by changes properties of you form that you'd find in the appearance section of the property grid. You could change them programatically. Another thing is to apply simple images to the background of the form and to different buttons and other control. Most controls support the property BackgroundImage.

On the other hand, if you want to apply more advanced method of making transparent forms, or forms with irregular edges, I advise you to read about GDI+[^] in the articles section. Once you know how to display form in one skin hardcoded, you can store different variables -eg, colors, dimensions, images, etc..- in external files, and ship them as skin patches for your application.

How to gain access to advanced file properties? For example, I want access to file version Other Version Information comments. Or file summary title and comments. I was hoping FileInfo would have that but from what I can see it doesn’t

Thanks

Hello

I think you are talking more bout metadata? They are stored in the filestream itslef. In the Audio section[^] you'd find to articles about extracting metadata.

Well the stuff over in audio is specific to WMF so it's not much help. I’m looking for metadata from NTFS. I’ve googled ‘file properties dialog’ ‘ntfs metadata’ and many other combinations and synonyms of these phrases. All I want to do is programmatically right click on an exe and view its version info.

Thanks though. I can't belive this is so hard. It was supose to be a QnD utility
