Hi all,
I have created windows application in c#, it is Sample.exe,
If this exe is already running, andmeanwhile if double click and initiate one more instance of Sample.exe it should point to already running Sample.exe.
Concept is simple if my windows media player is running say a movie file is being run.
and if I launch media player from shortcut it will still show the already running one instead of opening the separate media player.
Is it possible to do so for my application, how can I apply same logic to my Sample.exe
Thanks,
ashok

What do you mean by "lock"??
|
|
|
|
|
the .dll file can't copy the other drives, it's lock the file
how?

Not possible. The .DLL file can be copied when your app isn't running. There's nothing you can do to prevent it from being copied. Why? Because if you prevent the file from being read (that's all a copy operation is), the app won't be able to read it either and execute the code in it.

Hi
I have developed an application with .net framework 2.0 using C#.
Is it possible to run this application on third party machines without the need to install the .net Framework?
Thanks

Thank you, I checked the Xenocode PostBuild and it seems it could fix the problem, but it is way too expensive, isn´t there something cheaper?

Nope. Every one I've seen is $1,000 or more.
|

|
|
|
What is PostBuild's reputation? Is there something that is considered better?
|
|
|
|
|
Hell if I know. I don't use them, nor do I recommend doing so.

First and foremost, Service Packs for the .NET Frameworks. Every one of them has had at least one so far. The service packs cannot be applied to the application once "baked" by one of these utilities.
Second, depending on how much of the framework your app is using, they can generate massive .EXE's for deployment. And, if you have a bunch of these apps built with the .NET Framework baked into each, the collection can suddenly have the same framework multiple times for each .EXE.
I've heard of problems or total non-functionality of Reflection with some them, though I haven't bothered to test these claims either way.

Normally, it's not possible. It is is you buy third party tools, that cost upwards of a couple of thousand dolloars, that compile the required .NET Framework pieces into your app.

Yes, you can run C# applications without the .NET framework installed, but only if you have the MONO framework installed.

Hi,
I'm a winform aplication, and i have a problem with buttons shortcuts, for example i have a button with name &Ok and if a press alt+o or o the button action is fired. The probem is that i just want used the shortcut alt+o and disable the other. I know that i want catch the keypress event but i like to known if exists other way to do that.
|

AFAIK there's no other option than handle the keypress. However, the shotcut key (O in this case) shouldn't fire the button click unless the focus is on the button. If focus is somewhere else, only Alt+O fires the click.
|
|
|
|
|
The problem is the click button event is fired even the focus is in another control unless the control is a textbox. For example if the focus is in a radiobutton and i click in key "o" the click event is fired.
|

This was a bit surprise for me also but it seems that way. Many of the controls don't behave like this (combo box, listbox, listview etc) but radio button does. Also it doesn't matter which button has the focus. Still plain O will fire the click.
Since thise controls behave like that, I'm not certain that handling keypress will actually help. I think the only option may be to use KeyPreview and handle mnemonic characters centralized on the form.

I am not sure if this is possible at all, but lets say I have a listview with one item in it and I also have a textbox on the same form. Is there any way programmatic way make is so that the visible text in the listview item (listview1.item[0].text) is bound to the the text of a textbox? So, if I type a name into the textbox, it automatically updates the listview? Or, do I need to update the listview every time the text in the textbox changes? Someone told me how to do it with databindings and a listbox, but I need to use a listview.
