• Visual Studio Express Editions About Mutex veriable

  Hi, I have a problem in mutex veriables Actually I want to create a mutex variable and use it in another aplliaction which I have to run from current application. So How should I create the mutex variable and use that in other application and also how should I run another exe from a current application Pls help me out waiting for reply Thanks, Nilesh The following should work, the idea is pick a name for your mutex, then each application attempts to open a mutex with that name, if the mutex cannot be opened then assume it has not been created and create it instead. Named mutex's are global kernel objects so are accessible from multiple applications. const char* conMTXNAME = "MyMutex"; ...Show All

• SQL Server SSIS - Connection String Issue

  Hi I have been trying to resolve a connection string issue all day, and havent figured out whats the problem. I keep getting the Acquire Connection error everytime I run my package. Can you someone review the format of my connection string, and confirm that it is indeed the correct format: I have two conn strings specified in my config file, one is to connect to a remote database and one is for local. I have validated the connectivity from my server to these databases via Management Studio, and it seems to connect fine. But when I run my package it keeps failing.

• SQL Server Bulk Insert fails. Column is too long in the data file

• SQL Server Alternative for Cursor use

Structure of table is Id int CourseId int Chapter varchar Sequence int and sample data is Id CourseId Name Sequence 1 92 Chap1 1 2 92 Chap2 2 3 92 chap3 3 Now, when i delete second record i.e. Id=2, I want that sequence of Id=3 should become 2.

• Visual C++ Floating point stack overflow

  My application works fine in VS2003, but in VS2005, it is producing an overflow of the floating point stack.  This seems like it must be a code generation error in the new compiler.  Has anyone else experienced this problem In the particular case I am looking at, I step through the instruction FLDZ in the disassembly window.  Instead of getting a zero in ST(0), I get 1#IND, and the SF and C1 bits are set in the x87 FPU Status Word.  The first time through this code it works OK, but this second time through, the FPU tags register shows that the stack is full before the FLDZ instruction. Let me put some of my codes here to describe the problem: DOUBLE tempAngle = 0; DOUBLE one_minus_cosine, cosine ...Show All

• .NET Development Fill dataset

  Hi! I need to fill a dataset from lines of text that I pull from a tab-delimited text file. I think I need to first create a datatable to define what gets loaded into the dataset. Eventually, this data will have to go into a pre-existing database. How do I iterate each line from the streamreader into my datatable Thanks! sure. this will be tricky, I guess you can do a split, something like: string[] firstRowOfData = theStreamReader.ReadLine().Split(new string[] { "," }, StringSplitOptions.None); this will split the current line string, into several items in the array (think of it like columns I guess) and the point of splitting will be the comma "," - which can be replaced by whatever identifie ...Show All

• Software Development for Windows Vista How to assign task to user via rules and rulesets

  Hello, I have a sequential workflow that uses custom activities and a custom tracking service to generate task lists. End users will monitor for and work their assigned tasks. Question - how to initially set the "Assigned To" on the task or custom activity at runtime based on workflow parameters or other app domain data, and the current task. Requirements Prefer to use rule sets / policies to stick with declarative model and allow on the fly changes to work flow instances. Possible Solutions Place a Policy Activity just before each custom "TaskGenerator" activity in the workflow...add rule(s) to determine initial assignee on the corresponding custom "TaskGenerator" activity. This seems aw ...Show All

• Visual Basic Inserting a line break in a literal string

  I am just getting started with VB and I am sort of used to QuickBasic, and I wanted to open a text file such as "C:/File.txt" and add to it. I got the file open and all of its contents into a string, but I can't add line breaks to it. The line breaks display fine in a MsgBox command but I can't insert the line break string (which looks like two vertical lines) into a literal string. If I try to paste it into the VB Code window, it actually adds a line break just as if I had pressed Enter, and the symbols look different than the Shift + \ line ( | ). The program looks sort of like this: FileContents = My.Computer.FileSystem.ReadAllText("C:\File.txt") Now, a Sub for a button NewData = TextBox1.Text FileContents = FileCont ...Show All

• Visual C++ Can I build a 32-bit application with 64-bit compiler tools

  I'm working on a 32-bit application, and the build process takes very much time. Since 64-bit programs are usually faster than 32-bit ones, and I use the 64 version of XP, it would be great, I could build my project with 64-bit compiler tools. First I changed the executable file path in the VC++ directory settings from $(VCInstallDir)bin to $(VCInstallDir)bin\amd64, but it did not work. It seems the 64 bit compiler can only compile to 64-bit binary. Is there a way to speed up the compilation of a 32-bit application on a 64-bit system, that is able to run also 64-bit programs. Tbyte You may have right. I'm really in lack of experience of comparing 64-bit and 32-bit applications. Almost all of my programs ha ...Show All
