• Windows Forms Drawing Lines between two Listboxs

  Hi, I have two listboxs on my form that contain different fields from two tables. I need to be able to map these fields to eachother, kind of like the way SSIS works, but I am running into a lot of issues. I know that in C# there is no Line control so I created one myself but the thing is when a line has to cross over another one it somehow overlaps the other one, Now if I want to give up this Line control idea and just draw lines between fields then I have no control over lines for instance when the user scrolls down or up these lines have to move accordingly. Any feedback, ideas, solutions would be great. Thanks, Ryan How about the following: Create a graphics object from the form or pa ...Show All

  Hello there every1. First: Excuse my english, I know its pretty bad. I'm learning it too! My name is Ricardo and Im learning some advanced scripting techniques, so, here's my first question to all of you: At the beginning (even before) of the page load, I do something like this: Object.prototype.saymyname = function(){alert(this);}; Well, when all loads (onload), I create some new nodes, with the document.createElement(...) but, when I tell that new node to yell me its name...it doesn't know how to do it. var tmp = document.createElement('div'); tmp.saymyname(); Then: var tmp2 = new Object(); tmp2.saymyname(); --> it does '[object]' Is there something wrong what should I do I mean ther ...Show All

• Visual Studio Express Editions What does it take to run you own program?

  My question is as the subject says: What does it take to run you own program I created my own program, put it on a floppy and tried it on an other computer... But it doesn't work... i get an error and this is the error signature. I think this is weird because i have the same version of windows as on the pc I developed the program on(Windows XP SP2) and i have .NET Framework 2 installed.

• Visual Studio Team System CTP7 Download Location

  We are happy to announce that CTP7 is already here, no need to wait till next Monday, here it is! http://download.microsoft.com/download/3/1/9/319c5020-0fed-4dc1-b043-69567fda3941/TeamDataCTP7.exe CTP6 was only released 2 weeks ago, so what changed We added how many errors/warnings you want to see and make it configurable. We added the ability to suppress warnings same like in a C# project. This way you can selectively filter out warnings caused by 3 or 4-part name references. We made the warnings and error numbers explicit so no more overloaded meaning errors and warnings, I will post a list of these in a while combined with examples on when the will occur. We allow you to override the project SET properties for ...Show All

• Windows Forms Serial Number Generation Avoiding Duplicates

  hi i have a datagrid, and i have binded it to a dataset, i have a column called srno and its autogenerated, it works fine, the problem is when i enter the data for the first time in a row the srno is 1, after entering the data i navigate to the second row, at that time srno is 2, before entering the data in the 2nd row do some alterations in the first row, after finishing alterations in the 1st row i return back to the 2nd row, and suprisingly the srno is now 3, need help thanks Prasenna I would use the currency manager's position changed event to figure out the Id.

• .NET Development Fatal Flaw in the Large Object Heap?

  Hi All, After playing with the GC I find the following interesting. The problem domain I typically work in requires the allocation of very large arrays for image processing. We have discovered some issues when our processes are long running. We run out of memory and can not reclaim it. Our only recouse is to restart our processes. In an effort to discover why I uncovered the following: The LOH (Large Object Heap) is never compacted. I think this is a fatal flaw in the GC. I understand MS stated reason for this, but shouldn't there be someway to compact the LOH if necessary, at least a method call that forces the issue Does anyone know of anything that can be done Any workaround is better than killing the process... Here is a demo ...Show All

• SQL Server Server Migration

  I'm migrating 15 user databases from one server to another. The current production server is Windows 2000 Server SP4 and SQL Server 2000 Standard Edition SP4. The new production server is Windows 2003 Server and SQL Server 2000 Enterprise Edition SP4. The new server does not have the same directory structure as the current server. I plan to detach the database, move the .mdb and .ldb files to the new server and then attach the database again. I'm not sure what to do with the master and msdb databases. Do I need to bring over the master I know I need the msdb for all the job information. Since these are system databases, do I need to follow a different process I want to get all these databases over to the new server so I can begin some ...Show All
