Generally this means that the pause created by the breakpoint, fixes a race condition. Try putting a sleep before the code in question, if that fixes it, try to work out what your race condition is.

Thanks a lot Christian Graus,
My problem is solved by putting sleep....
Also I understood the basic cause for that..........
Thanks for ur quick support.....

I've been been tasked redevelop a bespoke application that's showing its age, it's functionally very rich but it's UI is circa Windows 3.0 and it's internal architecture makes it costly to maintain. It's written in C/MFC with a proprietary "database", it's genesis goes back to the late '80's.
The stakeholders agree that the application cries out for a dock panel interface a'la Visual Studio etc. I'd really appreciate knowing what products folks have used to implement a dock panel user interface and their experiences in doing so - rolling our own is not an option we would want to persue.
I've identified five potential sources for a dock panel control, please tell me of any others. My client is a non-for-profit so the budget is limited, but it's not zero. Major considerations include access to source (free, escrow or pay (within reason) are all acceptable), robustness (even at the expense of some functionality), support costs & quality and documentation.
AvalonDock - open source, free, lives at Codeplex, it's a "vanilla" dock panel control, it's the successor of http://www.codeproject.com/KB/WPF/WPFdockinglib.aspx[^]
Nevron UI for .NET - proprietary, costs US$169, this library includes other stuff beside Dock Panel, which has some attractions
JastDev Docking Control - proprietary, costs US$78, supports XAML Browser Application development which has some appeal, does not include much other than the dock panel control.
Actipro - Docking & MDI Control - costs US$149, includes a fairly extensive set of atomic controls. Actipro have a bundle for US$499, that adds ribbons, navigation, property grid etc, this too has some appeal.
Dock Panel Suite - open source, free, lives at Source Forge, it's a vanilla WinForms dock panel control (I missed this one in my original post, thanks to John Simmons for reminding me of its existence)

I guess a big question is, do you want to use WPF, or not / At least one of these seems to be WPF ? Are they all ?

You're right they're all WPF. Its what my search turned up.
Actipro has a Windows Forms Dock Panel in a suite with Tab Strips, Navigation etc.
There were some el cheapo WinForms controls which I rejected, some were moribund, i.e. they'd not been updated for years, or their mail addresses bounced or their forums had not had a post for 12 months or more etc.
I'm not enamored with WPF, because I'm not convinced that XAML is an efficient declarative language. Seems to me that there are too many ways of doing the same thing and no clear guidelines on what to use when, but I really need to use it anger to make a rightful judgement. I originally thought C was rubbish when I was writing PDP-11 assembler, so I don't take much notice of what I think.
Office 2007 is an influence, client recently upgraded to it, being who/what they are they get academic pricing. Apparently the users wanted their menu's back but after a few weeks they all got to love the ribbons etc, now they complain about Outlook not having ribbons & orbs.
The users don't know/care if its WPF, XYZ or �(, but they've seen things like the Health Care facade that MS did in the UK and they've indicated like some of that. Also given that the current system was bleeding edge when it was developed nearly 20 years ago, they're of the view that if they do they same again then they'll get 20 years out of any new system.
So do I want to use WPF, probably not, but do I expect to use it - probably. I may need to find someone with WPF skills and a heart of gold, i.e. willing to work long hours over a couple of years for shirt buttons.

We're currently using DockPanel Suite[^]. It does not use WPF.

I've got that too, it somehow slipped off the radar screen when I was writing my OP here. I hope you wont object to a few questions
Given it hasn't changed since Nov 2007 can I assume its robust?
Have you run into any coexistence problems with other controls?
My preference is to use VS9 and NET 3.0? Are you using VS if so which version, and which .NET do you target.
If you took another job and you were looking for a Dock Panel Control, would you look further than Dock Panel Suite, for reasons other than curiosity - in other words what deficiencies do you perceive in Dock Panel Suite?

It seems to be pretty solid. The documentation quite frankly sucks, and you have to glean useful information about its implementation from the sample application, but I've managed to get it going without too much fuss. I had to implement my own MDI child tabs but that was no big deal really.
urbane.tiger wrote: Have you run into any coexistence problems with other controls?
Not yet. We have a single docking window with four content windows, each of which contain a splitcontainer that has a treeview in each pane.
urbane.tiger wrote: My preference is to use VS9 and NET 3.0? Are you using VS if so which version, and which .NET do you target.
We're using VS2008 and dotNet 3.5. I believe the current version of the library targets 2.0, but when we converted it to 3.5, there were no issues.

It feels heavy to me (but I don't have anything to compare it to. There are also some features missing that I wish it had, like a MDI child tabs strip, and a couple of other things I can't remember right now. It's certainly cheaper than the other stuff out there. If I were in charge of a development shop, I'd probably prefer a commercial product, because with something this complex, support and documentation are critical factors (you don't want your devs sitting around with their thumbs up their asses waiting for an answer to a question, or wishing they could get one).

Hi John
Thanks very much for your thoroughgoing response. I guess I've anticipated that a Dock Panel Control will be a fairly weighty creature, Avalon Dock looks similarly "heavy", the commercial ones are probably even more so.
We'll probably make in decision sometime in Feb09, if you're interested send me a PM & I'll try to remember to let you know which way we go - assuming we go some where, can't be sure of anything these days.

How to display images randomly from a file on click of a button in C#.net
|
|
|
|
|
Well, you need to look at the Random class. Then you can use Directory.GetFiles to get a list of files to randomly select from.

You forgot to include ", and using google would probably have given you an answer a lot faster than waiting for someone here to try to figure out what you really want."

using the timer control, u can do this.
in the event of the timer , include some code. First, you need to add some images in the imagelist control. Than, in the timer event display a image from the imagelist use the break statement to break the loop . when ever the timer event occurs then the image changes . After the imageslist reaches the last index then make the control value as 0 to repeat the loop

You've asked us for the full source to a program. You can pay people for that on sites like rentacoder. We help beginners who buy books, do research, write code and need specific help.

I want to send message through windows' XP default firewall setting and it should be not necessary to add additional program (such as tcp or udp server program) at destination machine. Because I cannot send message using "net send" to my LAN users who use Windows XP with default firewall setting.
|
|
|
|
|
Your messages aren't going to be received by voodoo magic. Any socket connection need a server AND a client.
|
|
|
|
|
But, you need to not only do that, BUT you need to get through the firewall. So, voodoo is plainly what's needed.

I don't think you're grasping the core issue. It's not if this can be done, it's that you say you want to do it, but you've not even tried. No-one here is going to write it for you. If you were to write some code, we'd be happy to help correct it.
