• .NET Development Parsing double value from a string

  Hi all, I need to parse a string which is in the following format (example): -0.0004 USD/Tonnes Basically, it will be a double value, might be preceded by the negative (-) sign and followed by <Currency>/<Unit of Measure> . The result should be just the double value (with the sign if its there), as in the above example, it should translate to -0.0004 I wanted to know if there is an easy way of doing it in C#, like using the Double.Parse() or the string.Format() methods (I tried them both but couldn't get them to work) Or do I have to parse the string character-by-character to get the required result Thanks in advance, MadMonk P.S.: Apologies if its a silly question, I'm still a newbie in .NET ...Show All

• SQL Server Complaints about SSIS

  I'm sure Microsoft has heard most of these complaints many, many times, but I just have to rant about the issues I've encountered with SSIS over the last few weeks. Basically, SSIS, IMO, is a pile of dog ***. Yes, it gets the job done, but only in an extremely inefficient fashion: Objects are ID'd by a GUID. This means that, (for instance) if you change a connection by deleting an existing connection and replace it by another, all of the objects using the old connection break -- EVEN IF YOU USE EXACTLY THE SAME CONNECTION NAME -- because they only know the connection by the GUID. Deleting the old Connection, even if you rebuild the new one with exactly the same name, pointing at exactly the same server, etc., breaks everything because a ...Show All

• Visual Studio Tools for Office How to merge 2 Word docs, and also 2 Powerpoint presentations?

  Hi, Not sure how to go about doing this one: I've got 2 word documents that I want to merge into 1 document programmatically, using .NET - any thoughts I also need to do the same for 2 Powerpoint presentations Thanks Hi Neal Best to ask this in the Powerpoint newsgroup. You'll find some object model help, here, but the forum is targeted mainly at the VSTO technology.

• Visual C++ How to overload the ">>" operator for a user-defined type

  Hi, I have a Location class in my project, and I need to read a Location object by using cin >>, eg: Location locationObject; cin >> locationObject; I'm wondering if there is a way to overload the >> operator for a user-defined type like this. I trid to code the overloading method: istream& operator >> (istream& is, const Location& addLocationObject) { return is >> addLocationObject; } The compiler does not complain, but there is a error at runtime when the >> operator is called: "Unhandled exception at 0x00414219 in C++Project.exe: 0xC00000FD: Stack overflow." and it's pointing at the second line of the method above.

• Windows Forms TextBox with AutoComplete

  Hi, I am trying to populate AutoCompleteCustomSource (for my TextBox) only when the user hits the <Enter> key. I.e. when the user hits the <enter> key in the TextBox, i want to (a) send the text to the server, (b) do a server-side search for matches, (c) return the set of matches to the client, (d) populate the AutoCompleCustomSource programmatically, & (e) then display the matches in a drop-down. The difference here relative to how one normally sets this up, is that i want to issue a server-side request for the list of matches, & dynamically populate the AutoCompleteCustomSource. Now, i am able to do (a) thru (d), above; just not (e). Any idea how i'd do this Thanks, Mark ...Show All

• .NET Development Socket or Remoting in this scenario?

  I am investigating how to build a cache server which can be access by multiple web apps in a web farm. However, I am not sure should I use socket or remoting to handle the cached data transprotation in the network. The scenario is: The cache system maintain a list of cached objects. Clients (web applications) will send a key to the cache server and the cache server will send the cached data back if the data exists. The data sending back could be large and could be any type of custom class. The web applications will have lots of users in future so the performance of handling large amount of requests is critical here. I need some suggestions on which approach I should use. Also, some ariticles mentioned .NET will cache sockets which will be ...Show All

• Visual Basic Detecting Mouse Events in VisualBasic Forms

  Hi all, Just wondering if any of you guys could help me. I have setup a form with some buttons and an textbox, and i would like the textbox to display a message in it when the mouse hovers over a button.

Question 1: Is MousePosition the same as MouseHover Question 2: What do i have put after MousePosition/Hover so that it picks up movement over the mouse. Also, does anybody have any sample code for this kind of project ...Show All
