  Hello, i'm trying to read a ascii text file using the streamreader. For simplicity, let's say my .txt file contains the following data: a b c d e f g How would i read from, let's say the first occurence of character "c" to "f" It would read 3 lines after "c", up to "f", and give me: c d e f I understand how to read the entire file, but i do not know how to read it from a specific line, and 3 lines after that. I would appreciate your help please! Thank you for your time guys, the code works great! I used While tr.Peek <> -1 instead of the inifinate loop. ...Show All

• Visual C++ Rebuild using shared precompiled headers doesn't work

  To combat a long build time, I consolidated common headers across 20+ projects into a single precompiled header, to be shared.  The pch file is generated from a separate project (pch.vcproj with stdafx.cpp/h), and it works with clean builds and incremental builds (from editing one of the files belonging to the 20+ projects), but I get compile errors when I choose Rebuild.  Before presuming a bug, I'd like to ask the forum for help.  There are several things that have to be done to get this to work, and unfortunately, I'll have to reveal them to legitimize asking for help.  For sake of generality, lets say one of th ...Show All

• .NET Development SoapExtension Problems

  I'm attempting to create a Java web service with Apache Axis 1.3. One of the requirements of this web service is that it must maintain conversational state. Following the advice of an article here:   http://www.oracle.com/technology/pub/articles/davydov_soa.html   I implemented a JAX-RPC "Handler" to intercept incoming requests to my web service for an expected SOAP header. The end result of this is that the WSDL generated by Axis doesn't contain any mention of the SOAP header, but if client requests don't contain the expected headers, my service throws a SOAP fault...   Following directions in Axis documentat ...Show All

• Software Development for Windows Vista about "StateMachineWorkflowInstance.EnqueueItem "

  what's the meaning of " StateMachineWorkflowInstance.EnqueueItem () " when and how could i use it Victor - all of the communication between a Workflow host and a workflow instance is done via a system of low-level queues. EnqueueItem is used to send a message to one of these queues. The HandleExternalEventActivity is actually a higher-level implementation based on interfaces built on top of this queueing system. You'd use EnqueueItem whenever you where using a StateMachineWorkflow (although WorkflowInstance also has a EqueueItem method) - and you are using the queueing system directly (i.e. not using HandleExternalE ...Show All

• SQL Server For Each Loop Oddities

  I am experiencing some odd behavior in the Foreach Loop Container and was wondering if anyone else has experienced this. I have a SQL statement from a staging environment that populates an ADO recordset. When I created the variables in the package I specified them as the types that I was expecting (1 Int64 and the rest as strings). However, I kept getting a type cast error when it tried to run through the loop, this error only came about on the Integer column, which I believe was due to it being the first column. The only way I was able to resolve the problem was to set each variable type to DBNull after that it made it entirely through the ...Show All

• Visual C# Why are my Toolbox components dissappearing or unavailable?

  All of the components in my Toolbox window are greyed out and my custom installed tools tab has dissappeared. The only way I can regain the use of the components is to exit VS and restart. I have made sure the components are checked in the "Customize Toolbox" window. Can anyone shed some light on what is going on James, Thanks for the offer of help. However, I reset the toolbox and re-installed my third-part components. Everything is working normally again. I'm not sure what happened. I'll let you know if it happens again. ...Show All

• .NET Development ilasm.exe /OWNER parameter

  Hi, There used to be a parameter call /OWNER in the ilasm.exe which allowed me to assmble a dll/exe so that noone else can disassemble it without the correct /OWNER.

• Visual Studio Express Editions Windows.Forms.Form.Closed event

  Should I enter Me.Dispose in order to free all resources Why is this event not included when converting from a VB 2003 project (neither is .Closing by the way) The Closing and Closed events have been superceded by the FormClosing and FormClosed events. You shouldn't need to call Me.Dispose when the FormClosed (or Closed) events fire if you dispose of the Form correctly: If Form.Show is used and the form is closed, you do not need to dispose of the form. If Form.ShowDialog is used and the form is closed, you do need to dispose of the form. I have actually discussed this at length here: http://forums.micro ...Show All
