.NET Development Ping timeout < 500 ms
Hi, I have to connect to many machines defined in IP addresses ranges at startup. In these ranges, it is possible that some IP addresses does not exist or some machines are not started so I Ping (using System.Net.NetworkInformation.Ping) each IP address before trying to connect to it to prevent big Tcp timeout. It seems that, whatever timeout I specified < 500 ms, a Ping timeout is always at least 500 ms ! As I have to ping a lot of machines, I would like to specify a timeout of about 100 or 200 ms. To avoid too many threads, I send the ping sequentially in 1 dedicated thread. Thanks in advance, Droopy. OK though 25 times the average response timeout doesn't seem to me really small timeout. Thanks a lot ...Show All
SQL Server Fetch text from HTML [URGENT]
Hello everybody, I have data in my sql server table that is entered with a rich text editor so it contains html formatting. I need to show this data on the form with the formatting user has specified while entering the data. On the crystal report, I need to show the data not in the html format but simple text. I created a stored procedure to fetch the data and binded the report with the stored procedure. When data is printed on the report, it shows HTML tags with the data. Is there a way to fetch text in SQL so that report will only show text without HTML formatting Thanks. You can use the following code to replace all the HTML tags....

.NET Development Regex character classes in C#
Hi! I'm trying to get certain texts from an html source file. I tried to use regex and came up with a pretty good formula. It is as follows: ( <=person_id=)"[^"\r\n]*" It extracts the values of the person id fields by checking if the string is after "person_id=" and if that's correct, it checks right after "person_id" for any string between double quotes, excluding the stuff I enclosed in square brackets. For example from person_id="443245" it gives back "443245". This works all good in PowerGREP (a regex editor) but when I try to use it in c# I get error after error. My whole code is somewhat like this: string SourceString = File .ReadAllText( @"C:\textfile.txt ...Show All
Visual Studio Express Editions Preserving File byte value - Help.
My application reads and writes files of any type as array<wchar_t>, through the Binary Reader and Writer. The intent is to read in most of the information and then write it out to a new file unchanged. I find however that this doesn't work with all files. Files with text characters - such as the .sln file of VC++ 2005 express- work fine. However files such as the .suo file do not. Information is lost entirely. The final file sizes should be identical but in fact the output file is smaller by at least 1K. The application reads into one buffer and then writes out to the new file from the same buffer. The buffer is quite large (30K bytes) compared to the file (17K) so it should read in the whole file and spit most of it out without a p ...Show All

Software Development for Windows Vista Can't create more then seven VMR9 renderes.
Hello, I have to create 16 preview panels on main window with images drawn from specific data. I am able to see 7 panels filled with data, but I get error: -2147220969 while doing hres = g_pCapture->RenderStream(0, 0, pSrcFilter, 0, g_pVmr). Is there any limit with number of VMR9 instance I need to display 16 previews of different data result. Regards, Peter I have seen this discussed in other boards, and have done some tests myself. The limit seems to be hardware dependent, but always in the same order (7 to 9 instances). You might be able to create a few more instances (up to 12 or 15), but the last ones are non-functional. You do not get this problem with VMR7, you can create tens or even hundreds of functional instan ...Show All
SQL Server Formatting a Subscription Comment
I have looked everywhere for an answer for this one, so if it's out there and I've missed it, sorry. I want to include a list of instructions with a report that I am sending out to a list of subscribers (not Data Driven, each is an individual subscription). It seems no matter how I enter the text in the Comments box, the body of the email comes out as a continuous stream of text with no line breaks, which is difficult for the recipients to read. Is there a way to embed line breaks as a minimum, but preferrably additional formatting, in a subscription comment Thanks Trevor Trevor, Did anyone answer this I have the same question. Thanks.
