Thanks alot for replies, so far i got that we should take alook at our design again, and try to seperate db engieen and OLAP to be in two servers instead of one, :) Am i correct?

I got a requirement for a buisness web application that will handle 100 concurrent users requests. we designed our data tire. we will use SQl server 2005 and we will use OLAP services. the question is how can we determinate the best physical hardware requirment for database server. i mean we need to know min phyiscal memory size , processing power. for the server that will be managed by windows 2003 server OS. known that the client wants max page loading duration on max load(100 concurent users) is 8 seconds. Note: 1-we did tried to set up server with 2 giga ram, and dual core processor. on first 30 concurent users it was ok. after user 50. the processor,memory utilization is 100% and things got worse . over 60 seconds per page 2- we use tool to test performance that simulate 100 users request the application every second.:confused:

hello all, i got a very serious problem and i need to add http header to each client request i make to a webservice. so my question is how can i add a custom http header to the request? as .net generates wsdl and hide the httprequest object? i wanna see how to access the base httprequest object and add the header i want. thank you

Response.Clear(); Response.Buffer= true; Response.ContentType = "application/vnd.ms-excel"; Response.Charset = ""; Response.AddHeader("content-disposition", "inline;filename=MyExcelFile.xls");

hi all, i got a small problem but its really annoying. i want to use the new implicit localization feature of asp.net 2.0. i created default resource file in local resources folder say def.aspx.resx thent i created number of resources files with diff languages like def.aspx.fr-FR.resx. the defualt resource file works greate but when i change culture and uiculture to another culture say fr-FR. nothing changes and the resource file def.aspx.fr-FR didn't loaded i dont know why??? it works only when i make it as defualt resource. def.aspx.resx but changing cultrue anf uiculture doesn't work!!!! Thanks in advance. marcoryos

hi all, Listen i got a problem and i don't know it's cause. when i run that piece of code: grf = Graphics.FromImage(metafile); //do what ever i want with grf grf.Dispose(); grf = Graphics.FromImage(metafile); i got an out of memory exception. i realized that if i created a graphic object twice from metafile i got that exception.by the way when i use normal image not metafile it works. i wanna know why that with metafiles? marcoryos

yes but the problem is when i got the data back i don't wanna parse it i wanna save it as its on xml file. The destenation program written in c standard so i have to change the the codes by my self into tages which headach i don't want to. is there any way to transfer file without allowing soap serializer to do soo. i tried to comment xml tages and use CDATA but it changes to:doh: marcoryos

hii all; i got a serious problem. i return an xml file in a string from web service. when its serialized the xml serializer replaces tages '<' with its unicode &.. which make a problem to me. how can i force the serializer to make some how my xml string const ,commented and don't change tages. by the way i don't want change values to tages again with my own i wanted to be back as tages. Thanks in advance. marcoryos

hii all; i got a very serious problem, there is two process that read/write xml files in the same time how can i control this with good preformance and without exception. thx alot for your time. marcoryos

hii all; i got a very serious problem. there is two processes that access (read/wite) xml in same time how can i control this without exceptions,with good preformance. marcoryos

hii all: am developing an Encryption algorithm and i have to read the input file as block of bits . the block length 512 bits. i store them in bitarray collection, the problem is how can i convert them back using c# to 64 bytes? marcoryos

hii all, Am working with sql server 2000,i have a series problem my database log file is expanding in unusual way; my data file(MDF) just 50MB but my log is 2 GB can u imagine that. i know i can restrict size but why its expanding like this? marcoryos

hii all, what is the Cache-Control and what is the diffrence between private and public cache? thanks alot for your time. marcoryos

why not? TcpListener is server socket. after u start it Listener.Start(); you can accept connection from Socket socket=Listener.Accept(); and you can know from socket as i mentioned above who you are connecting with. marcoryos

hiii, if you are using Socket class then after connection established all you have to do is: IPAddress addr=((IPEndPoint)socket.RemoteEndPoint).Address; marcoryos

u can do this with vc there is no hooking with c# on other applications windows messages. even if you used win32 hooking API's implicitly from c#, you will hook only your own Application Messages. marcoryos

hii all; is any one knows how to use "Push model" in client server communication or what is exactlly Push Model Algorithm.? marcoryos

hii all; i want ask some questions about network. 1-if am in lan and we connect to internet through proxy server. of course the proxy replace each request ip address of any machine on lan by his ip. the destination host will replay on proxy ip. how can the proxy determine the staion on lan who made original request to take response? also same question if i access internet in lan through (ics) for ex pc has modem 2- if i bind a sockt on lan its address and port will be on lan only. if this machine can access internet through lan is there away to bind it on lan router which access internet or i mean the interface which has direct access to internet so i can communicate with it from outside like imesh wich can work even if am in lan? marcoryos

hi all; i got a serious problem; iam making network application and am tring to send udp messages from any node on internet to node in local lan who has access to internet through serial router. the problem is when i started to transmite messages i found that i recieves his messgaes but he can't. when i traced the program i found that his ip and port is diffrent than what i bounded it on. of course the ip is the external ip of lan to connect to internet but the surprise here is even port changed!!!!!!!. i can know from udp socket the ip and port of sender but i need to know before sending or recieving becouse there is main server who control all operations and sends those info between node to communicate. so my question is how can i know virtual ip and port of node in local lan who deal through them to internet? thx for your time. marcoryos
