• SQL Server Using a Dynamic XML Dataset

  Is there a way to dynamically use an XML dataset as a datasource We got it to work. The problem that we are having is when multiple rows are returned in the dataset, it will not display them on the report, even though there is not a first wrapped around the Fields!whatever.value, the report is only displaying the first value that comes back. ...Show All

• Visual Basic chart type in run time

  hi i m using crystal report in web page. i want to give a facility to my client that he can change chart type at run time. pls suggest me that how can i implement this thing gorla, Unfortunately, this capability isn't possible yet (although I heard that this might be coming in the next version). The only way to do it is to create multiple sections with each type in each section. Then dynamically hide all the sections except for the one that has the chart type they want to see. A pain in the butt, but that is your only option.

• Visual C++ Why is the variable "components" (System::ComponentModel::Container) added?

  When a Windows Forms Application project is created in Visual Studio a variable named components (System::ComponentModel::Container) is added to the generated source code. But why I only see this variable accessed in the destructor: ~Form1() { if (components) { delete components; } } So, why is that variable added and how is it used I think the  components member is used when you add to the form an item from Components panel. For instance, if you add a Timer , then a line like this is generated:   this->timer1 = (gcnew System::Windows::Forms::Timer( this->components )); ...Show All

• SQL Server Replication problem in SQL Server 2000

  Hi all SQL Server experts! I have created replication on my two servers (production and backup servers). I used wizards to create it and then generated SQL script for deleting and creating replication. For another task I came across the command sp_removedbreplication 'dbname' and I tried to use that for removing replication more easily on the servers. It seemed to not remove everything on the production server and whenever I install replication now, either by using wizards or my generated SQL scripts I get an error icon (red circle with a black X in it) on my Replication Monitor all the way down to Publisher and the publication named with the computer name. Also this icon is on Agents and Log Reader Agents but not on the actual agent. ...Show All

• SQL Server problem scripting a BULK INSERT

  Hi, I'm trying to script the creation of a database. I've used Visual Studio to generate the scripts to create tables and views. I now want to script populating the data. Some of the tables contain a lot of data so I was going to use BULK INSERT but when the script runs, it cannot find the location of the data and format files. Is there a way of getting around this I can't use a fixed location. thanks Jason Do you know if the client you will be running the scripts from is remote or local If it's a remote client, than you would probably be better off loading the data using BCP. Assuming that you will use either SQLCMD or OSQL to run the scripts, it would be really easy to launch BCP using the ! ...Show All

• Visual C# Problems with Nullable DateTime Type.

  Hi all, I have a Class with a field called UpdatedDate that is of type DateTime.

• .NET Development xml serialization problems with asynchronous callback

  hey guys, im developing a windows application that uses asynchronous callback as network communication technique with xml serialization for sending complex objects over the network. the problem is that at receiving the buffer to be written to the file is never written fully and in correct format. its always cutted from the middle and so the serialization always fails. any clue thanks I'm also guessing you are having the same problem I had a while back - its the way TCP is, sending out data in bursts, so your reciever appears to read all the data it recieves but actually on the next read, the rest of the data just turns up. Are you also able to post the code for your recieving end, whe ...Show All

• SQL Server Soundex

  I have two tables in Access database. One table has 166,000 rows and another -75,000 rows. Both tables consist of the ids, names and addresses. I need to run a program, which was written in VBA, to find similar names and cities in these two tables, and then I need to populate the third table with id only from both tables. I forgot to mention I use Soundex function in Access. I try to run this program for 48 hours, and it still running. Do you think this is a good idea to use Access for this task Or could you please help me to find another solution Please let me know.
