Re: Socket Program>????? Heath Stewart27-Dec-03 5:07 Heath Stewart 27-Dec-03 5:07  You should debug your code. An XML file is no different than a image file or an AVI - they are all just a stream of bytes. If your app treats them as such (And your code indicates that you do), then your app doesn't care - at the time of transfer - what is in the files themselves. XML files are not these special files sent from God, but just a formatted document, formatted accordingly to certain "guidelines" just like the various image codecs and AVI codecs. The only problem I can see if your code is that you're writing out a binary file. Depending on how bytes are written or transfered, you may need to take file encodings into account. The only difference between the XML files you mention and the image and AVI files is that the former is a text file (ASCII, UTF8, Unicode, etc.) while the latter two are binary. There many be a problem in the way you handle text files. You should consider what FTP does, which is send such files using a text encoding while transfering.   -----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?

Dileepa Re: simple generic add,mod,delete Heath Stewart27-Dec-03 5:02 Heath Stewart 27-Dec-03 5:02  You can't take a table as a parameter. You could take a table name or a filename with a DataTable (serialized as XML) in it. Then use commands in the System.Data namespace (like System.Data.SqlClient.SqlCommand or System.Data.SqlClient.SqlDataAdapter) to do what you need. All the documentation is in the .NET SDK documentation and there are plenty of examples here on the CP site.   -----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?

Re: Printing Page Number Heath Stewart27-Dec-03 11:20 Heath Stewart 27-Dec-03 11:20  That depends on you - it's your code generating and printing pages after all. If you're simply printing text, you can get the height of the font, factor in the extra line height (which you control) and margins, and measure the string to print. From that you could calculate the number of pages. If you're drawing pictures and what-not, you calculate the picture size multiplied by any zoom amounts (percentages).   -----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?

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.

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?

I know nothing about 3D graphics. I know a lot about COM.

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.
