Clicking through transparent windows Anonymous25-Dec-03 5:06 Anonymous 25-Dec-03 5:06  I have a 50% transparent window that is on top of the desktop. I want the user to be able to click 'Through the transparent window' onto objects behind it ... my computer. The transparent window does not need force it just needs to be ontop of all the other windows. another example is .. if you press alt-ctrl-del to bring up task manager how can i program the window to pass mouse clicks on it to the window behined it, if task manger is my program? I hope this is clear enough to answer Re: Clicking through transparent windows Takeru Koushirou26-Dec-03 8:12 Takeru Koushirou 26-Dec-03 8:12  Maybe it would help to enumerate the visible windows, find the window laying under your window but top of all other windows and the click point lies in it's client area and pass WM_* event message to the window... Maybe there is another easier way to do that, but maybe this will help. Good luck ^^ -------------------------- xplo.re Project Management http://www.xplo-re.com/ multi-thread multicast server GTR3425-Dec-03 1:19 GTR34 25-Dec-03 1:19  is it possible to write a multi-thread multicast server? that mean one server can have many multicast group and serve different client? any reference website about it?? thanks a lot! Re: multi-thread multicast server Heath Stewart27-Dec-03 4:56 Heath Stewart 27-Dec-03 4:56  Sure, why not? You can make a program do practically anything you want. Search CP for examples, or google the net with appropriate keywords. Mostly, if you use the same multicast port for the different threads handling different clients, send some sort of identifier (client name/version, etc.) so the proper thread can process it and others can drop it.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

If so, what do I set in the build properties of the C# dll to create the .lib the C++ code needs? Re: Calling function in a C# dll from C++ code Nick Parker24-Dec-03 19:57 Nick Parker 24-Dec-03 19:57  Tom, you may find my article Creating a CCW for COM enabled non .NET applications[^] helpful, it explains how to do this. - Nick Parker   My Blog Last time I checked, all programmers have selective ignorance. I know nothing about 3D graphics. I know a lot about COM. VB gets under people's skin because one can be ignorant of computer architecture and ASM and still get a lot done. - Don Box How to find servers in a network Cristoff24-Dec-03 10:08 Cristoff 24-Dec-03 10:08  My network is broken and has dynamic IPs. Not all computers can be seen and accessed by their names. Is there a way to identify a server (or a computer) in such environment? I know that the best solution in my case is upgrading all computers to WinXP but that's not the issue now. That case makes me think if it is possible somehow to detect/identify specific computers (especially) servers quickly and reliably? Any ideas?

Re: How to find servers in a network LongRange.Shooter30-Dec-03 10:15 LongRange.Shooter 30-Dec-03 10:15  The question you are asking is really a very complex one, especially if you have no network internals knowledge. If it is a Windows network, the machines could be in a different workgroup (if you are workgrouping) or in a different domain (if you are doing domains). If everyone including the servers are in the same group, and you cannot see half the machines, then it could very well be an internal router problem (if you have a large network and are using routers with virtual networks). Also if you have a dynamic network, as in everyone uses DHCP, then the issues can be anything from the machines being misconfigured and do not see the DHCP server or someone really screwed up and there are two DHCP servers alive with completely different subnets defined. In that case your network is screwed up and needs to be fixed. If you can only see half the machines in the network using your machine, than no software you write will ever see the machines either. Server discovery (asking to get a response of who is on the network) would be a stupid thing to incorporate into a base development language since it would open a HUGE barn door to hackers everywhere. (ala, the heist of the HalfLife 2 source code but much worse) In previous applications I wrote code that worked with a specific sequence of servers (basically a primary and fallback server). I'd try to connect to primary. If an exception was raised that indicated no response, I attempted to connect to the fallback server. If I could not connect to either, then the application would not run. _____________________________________________ The world is a dangerous place.

The best way I can think of off the top of my head is finding the window for the address bar. Tthis will be a child window of the application's main window (or a child of a child, etc.). Take a look at the Spy++ application if you have Visual Studio installed. Basically you can use it to find windows and look at their properties. Once you find the window, you can look at it's properties and get the text within it. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Sites hebzzz24-Dec-03 7:56 hebzzz 24-Dec-03 7:56  hi would any body tell me how i can read URL written in browser bar Re: Sites Kentamanos24-Dec-03 7:59 Kentamanos 24-Dec-03 7:59  Need a little more info... Do you mean server side (getting the URL of the page basically)? Are you an application trying to get the URL from a browser running on the client? Are you hosting a web browser control?

From a separate application, get the Windows handle (HWND) of the Internet Explorer application (use Spy++ to find class information, but don't use the HWNDs there because they are allocated with every Window) and P/Invoke the native FindWindow function to get the Window with that WNDCLASS. Find the window class of the Address bar, then get that window and get its text by P/Invoking GetWindowText.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

Also, where I can find some more information on the win32 api. What I have is a magnetic card reader that connects to the usb port and windows picks it up as a hid device. I need to be able to recieve information from this device directly into my application, which is written in C#. Thank You, Nits Re: HID USB - Mag Card Reader Interaction Kentamanos24-Dec-03 7:07 Kentamanos 24-Dec-03 7:07  What magstrip reader are you using? Don't they provide an API of some sort? I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: HID USB - Mag Card Reader Interaction nitesh11526-Dec-03 8:51 nitesh115 26-Dec-03 8:51  The mag card doesn't come with a driver. It actually uses the builtin HID driver from windows. Thank You, Nits Re: HID USB - Mag Card Reader Interaction Kentamanos26-Dec-03 8:53 Kentamanos 26-Dec-03 8:53  So does it simply act like a USB keyboard and send the magstrip data like it was typed in? Do you have a model number so I could take a look at what you're using? I've used a few different products before (both MICR, magstrip, and a combination). I've seen magstrips that act like a keyboard and simply type the numbers in when you use them and others that are much more complicated. I, for one, do not think the problem was that the band was down. I think that the problem may have been that there was a Stonehenge monument on the stage that was in danger of being crushed by a dwarf. -David St. Hubbins Re: HID USB - Mag Card Reader Interaction Heath Stewart27-Dec-03 4:47 Heath Stewart 27-Dec-03 4:47  I typed "HID" into MSDN Online and found quite a bit of information. This is not a simple / short solution and isn't really appropriate for a forum. You should read the documentation provided in those links. As far as using C#, you might be better off writing a native module. You'll have to P/Invoke a LOT of native functions and recreate many structs, as well as define many preproc defs. If you use a native library with your app, you can make a few simple functions that you can P/Invoke that wrap the functionality you need, thus saving you development times and costs (if applicable). For more information on P/Invoking, see the .NET SDK documentation for DllImportAttribute.   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?

There is a LOT involved in drawing a tree. If you don't like this, derive your own and handle drawing in a separate thread, but there's very little you can do with the TreeView provided in System.Windows.Forms.dll. You could also look for a commercial solution like the UltraWinTree from Infragistics[^].   -----BEGIN GEEK CODE BLOCK----- Version: 3.21 GCS/G/MU d- s: a- C++++ UL@ P++(+++) L+(--) E--- W+++ N++ o+ K? w++++ O- M(+) V?
