• Visual Studio Express Editions Some creative inspiration...

  Hi Guys, I want to build a scrollable information-rich GUI list, rather like the list of emails in MS office. That is, a list of boxes, with each box containing a couple of lines including title (maybe in bold), some information, some numbers and maybe a couple of icons. What do you think is be best way to construct this I'm guessing many of you will say datagridview or some sort of custom control. These would be fine, but any help in terms of exactly how to do this would be really appreciated. Two things to think about: 1) I'm not an expert programmer, eg. I'm not completely sure how to do complicated inheritance. 2) I only have VC++ Express - can you create custom controls with this Any help appreciated - any good solution w ...Show All

• .NET Development Service Initiated Communication???

  I am creating a web service to be hosted on the internet and a client application in C# that will run on users pc’s. The web service should be able to deliver updated data to the client when random updates are made to the web service’s database, could be multiple a minute or 1 a day. My question is: what is the best way to trigger this communication between the client and the web service The clients can go online and offline at any time they so desire, but could be connected for weeks without disconnecting, completely up to the user. Is there a way to only have communication take place when the user logs in, an update takes place on the server, and when the user logs off. Basically is there a way I can have th ...Show All

• SQL Server Changing DataTypes in an Excel Data Source

  Hello. I'm importing some data from an excel file to sql server 2005. I created an Excel Data Source inside my Data Flow Task but it is assuming that the source columns DataType is double-precision float [DT_R8]. It isn't, even though some rows may containg numeric string in the column's cell.

• SQL Server Script length limitation?

  Hi, The answer to my question may depend on both the sql server engine and the data provider; I do not know enough about the internal goings on to judge this. Thus, I should mention that we are connecting to SQL Server 2000, from an ASP.NET 1.1 application using the SqlClient provider. First a short introduction to my scenario: We have an application that needs to support exporting and importing data between different instances of the database (in a disconnected manner). This has been implemented in such a way that the export generates sql, which is then simply executed on the importing side. (It wasn't me! I'm fully aware of a number of reasons why this solution isn't any good, but this is what I have to work with.)  This is do ...Show All

• Visual Basic Location of new child form in MDIParent

  Hope you can help. On creating a new child form in the MDI parent I am finding its initial location to be (-4,-23) and am unable to change it. If another child form however is added the older form repositions to (0,0). Is this a bug or am missing something Thanks Have tried "me.location = new point(0,0)" but this still fails to change the forms location after being shown. I am assuming that the child form is initially being placed at the location of the parent form and not in the rectangle of the parent form. hence -4,-23 is away from the inner rectangle to the outer border.
