• Visual C# Event Handler problem!

  Hi all, I have two forms (Form1 and Form2) and I'm using event handler to pass data back and forth between the two forms. In form1 I have a checkbox that when click will brings up form2 and when form2 cancel button is clicked will diselect the checkbox. But somehow that's works but after I clicked on the "cancel" button on form2, form2 popup again. Please help, I only want form2 to popup once not twice. Form 1: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace PassingVar { public partial class Form1 : Form { Form2 F2; private ...Show All

• Visual Studio Express Editions Can I create a win32DLL project with Express Edition?

  Hi, Can I create a win32DLL project with Express Edition - Arse ASP.NET_NewBie wrote: Actually, I am of the mind that you can create DLLs with Vsual C++ Express... I mean have you tried the http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/default.aspx . I think there is a way to create DLLs with this free version. Correct. To clarify, the Platform SDK isn't a version of Visual Studio. It's the collection of the libraries and header files needed to compile and link native Win32 applications. It's a free download, and once you have it you can start writing native executable code! ...Show All

• SQL Server Performance of Encryption algorithms

  I am in the stage of design for an application that uses SQL server 2005. We intended to encrypt some sensitve data using the encryption features in SQL server 2005. we will use symmetric key encryption. The question here is which symmetric encryption algorithm has the best performance how much does the key size affect the perfromance the data to be encrypted will be some lines of text equal to a word document. any ideas Hi Muhammad, We don't have explicit numbers for the performance of different algorithms/key lengths yet but from what we have seen there is no significant difference. The biggest performance impact is how the data is stored (i.e. storing encrypted data across very many rows in lots of columns and then selecting ev ...Show All

• Visual Studio 2008 (Pre-release) WCF equivalent to MapPath?

  Is there a WCF equivalent to MapPath I have some specific files that will be in the directory where the service is running. My question stems from the fact that MapPath bacially is called from a static HttpContext. I understand that this isn't a problem if the service is hosted in IIS but will there be an HttpContext for all hosting environments What would be the safest way to get the "root" directory of a WCF service Thank you. Kevin Burton HttpContext .Current.Server.MapPath There is an HttpContext only when webhosted in aspnetCompatibilityMode, see http://msdn2.microsoft.com/en-us/library/aa702682.aspx for details. I don't think there is an equivalent for other hosting environments. ...Show All

• Visual Studio Team System Team Foundation Server Collaboration Tools (?)

  Hello, I am on a new project, and we are all completely new to Team Foundation System. I’ve been tasked with researching what ‘collaboration tools’ Team Foundation Server/System provides, and to further investigate what features they have, etc. The type of collaboration tools/features we are interested in are: 1. Threaded discussions: a. This would be similar to a forum like this one, where a developer on the project could start a topic and other developers could post replies, etc. 2. Document Repository a. A repository where all team members can view the latest revisions to project documents, ERD’s, etc. 3. Announcements a. A facility where project announcements, news, etc, could be po ...Show All

• Visual Studio Team System Upgrade from Trial to TFS License

  We received our TFS License Key for our Server, but since our Server is already a critical server, I would like to know if there any issue related to the fact I will use the same TFS Key to do a rehersal on another Trial Server before doing the real upgrade (even if this upgrade seem to be simple as entering the key in the Maintenance mode of Add/Remove Program) I have done it , all it need downtime less then 5 mins , it does an IIS reset after you put the key in Maintenance mode of Add/Remove Program. I have done 3-4 upgrades of this kind and I never get any issue . as long as your key is okay , I don’t see any issue . ...Show All

• Visual Basic Unsigned Arithmetic and overflows

  I've had this discussion before with unint64s. Setting what would normally be the sign bit causes an overflow. Now I'm seeing this in unint32s. Dim a As UInt32 = System.Drawing.Color.Black.ToArgb will cause and overflow. Dim a as Uint32 = now.ticks and &hFFFFFFFF will cause an overflow depending in the time. This should not be. What it means effectively is the UInt32 is actually UInt31. Well, you get the same behavior as long as you tell the compiler what type the constants are. It's not big deal to add an UI suffix after all. ...Show All

• Software Development for Windows Vista Opening VS2005 Solutions in Vista

  When I work on Visual Studio Solutions I have always navigated through windows explorer and then double clicked on the solution to open it in Visual Studio. The MRU is NOT a safe way to open solutions when you have multiple versioned solutions on the drive all with the same name but a diferent path. Now how do I work open solutions from windows explorer as an administrator When I open atl com projects this way in VS2005 they fail to register after compilation. I can Run Visual Studio 2005 as an Administrator and then open the project from here and it is able to register but this seems extremely annoying to me. I thought Microsoft years back wanted us to be able to make things Document Centric. Is this over Is there a way for me to ...Show All

• SQL Server Wat's the syntax to insert unique identifier data?

  May I know what does the syntax of inserting data into a field of type Unique Identifier look like [code] INSERT INTO THAI_MK_MT_Log(GUID, Status) VALUES ('2331486348632', 'S') [/code] The "2331486348632" is to be inserted into a unique identifier field. If i coded the insert statement as the above, I got an error saying that "Syntax error converting from a character string to uniqueidentifier"..... Can anyone help Look at the function NewID(). It will create a new GUID value for you. This can be used for inserting. Also, from the Books on-line for NewID(), this example shows how to use a literal. INSERT INTO THAI_MK_MT_Log(GUID, Status) VALUES (NewID(), 'S') DECLARE @my ...Show All

• SQL Server supressing multiple data items on a report...

  I am sure this question must have been asked before. I have a report that has some header data in the body field. The problem I am having is that, if there ismore then 1 data row returned by the query, the "header" data lines get duplicated. I am using a grid control onthe report to display the data. My question is, how do you folks prevent the other rows from showing up. I tried using the surpress option but it just shows 1 row with data then 6 blank rows. Ideas Daryl I solved this problem when I discovered you could add more then one row to the datatable header section. Yes, I am a reports newbie. So this is no longer an issue for me. ...Show All

• SQL Server SQL Server 2000 MSDE

  Hi We have sharepoint installed and as per the developer MSDE was installed by Sharepoint. I don't know much about Sharepoint but I would like to administer the 2 databases created by registering it with Enterprise manager. We have licenses for SQL Server 2000 Standard edition (per processor license). Is it okay for me to register the msde and manage it graphically rather than using osql commands. Thanks.   This is a major stumbling block for developers. Somebody intimately familiar with the sql dll's and install could surely come up with a solution to get sql 2k installed I have dozens of customers and eventually they will all get to sql 2005 but for the next few years i have to support ...Show All
