View 1 RepliesI'm trying to connect to a sql server 2005 database. I'm using the following connection string.
Dim cnn As OleDbConnection = _
New OleDbConnection("Provider=sqloledb;Integrated Security=SSPI;Initial Catalog=Iconics")
Using this connection gives me the following error :
Error : Microsoft OLE DB PROVIDER FOR SQL SERVER : [DBNETLIB][Connection open(connect()).]SQL Server does not exist or access denied.
Does anybody know what is wrong with this connection string.
I can connect to both databases with SQL Server Enterprise Manager, so I know the servers are up and available. One of them is SQL1, the other is SQLTEST.In my program when I use the following connection string, it work connects just fine:
conn = New DBConnect("Data Source=SQL1;Initial Catalog=SignInspection;Integrated Security=SSPI")
However, if I change SQL1 to SQLTEST the connection times out I don't get any errors other than the timeout error.I can run the profiler on SQLTest and see that it is most definitely NOT even attempting to connect.
EDIT:Well, it's a moot point now because I got authentication working properly on our SQL1 server.
First off, the web server is running IIS and .NET. Users are logged in to the intranet using Active Directory, and the .NET page needs to retrieve their log-in credentials (username most notably). The database is SQL Server 2005, running on a different machine. But the .NET app needs to impersonate as another user to connect to the database.
To successfully do both of these things go to Windows > Run, enter inetmgr and hit run. Navigate to the site and right click > properties, then click on the tab titled Directory Security, click Edit.., make sure only Integrated Windows Authentication and Digest authentication are enabled. Enter your proper AD realm and click OK. Apply the settings/hit OK.In web.config you need the following lines
<authentication mode="Windows" />
<identity impersonate="true" username="myDomainMyUserName" password="123mypasswordgoeshere">
replacing, of course, myDomainMyUserName and 123mypasswordgoeshere with the username and password that has login rights on both your domain and your sql server. The connection string can probably be modified, but this is mine and it works:
Server=SQL1;Database=SignInspection;Trusted_connection=True;
One of my testers is testing my program that imports an XML file and puts all the data into correct fields in an Access database. He said on his Vista laptop he got an error saying: "Microsoft.jet.OLEDB.4.0 provider is not registered on local machine"
I know you don't have to have Access installed to run my program and I'm pretty sure all the OLEDB objects are in the .NET framework so why is it saying that?

View 8 RepliesI can't work out how to add nodes to a treeview as a child of a particular identified node.
The treeview.nodes.add function has seven overloaded definitions each of which seem to add it as a child of the root node. I can't find a way to specify the parent.
I've found this article which gives an example
TreeView1.Nodes.Add , , "root", "Root Item"
TreeView1.Nodes.Add "root", tvwChild, "child1_root", "Child1 of Root"
TreeView1.Nodes.Add "root", tvwChild, "child2_root", "Child2 of Root"
TreeView1.Nodes.Add "child1_root", tvwChild, "child1_child1", "Child1 of
Child1"
I've seen several similar articles with the same format. However this doesn't work. I get compilation errors. It doesn't match any of the function definitions, and tvwChild is not recognised as a constant.

View 3 Repliesso here is what I got so far. I have a treeview with multiple states as parent nodes. then as child nodes I have certain cities. as for my code - I have it set up that if I check the parent node, all children nodes will be checked. I also have code that moves the tags to listbox. the only items that have tags are the children. the code that I have works if I have tags set for the states, but I dont want to have parent tags move to the listbox. how can I change the code I have or rewrite my code to get ONLY children tags in the listbox even if the parents are checked??? hope this makes sense. here is my code
CHECKS ALL CHILD BOXES IF PARENT BOX IS CHECKED
VB
Private Sub TreeView1_BeforeCheck(ByVal sender As Object, _

View 4 RepliesI'm having a little trouble figuring how to do this.I have a dataset with a single table. Each row has the following fields ProductName, Version, CompanyName
The data might look like this
Visual Studio, 2005, Microsoft
Visual Studio, 2008, Microsoft
Office, 2007, Microsoft
I have already populated the TreeView with a list of Company names from a separate table. Now, what I want to do is to loop through my dataset adding a single node for each product under the appropriate manufacturer. Then under each product adding a separate node for each version of that product.

View 10 RepliesI have a TreeView populated with some nodes, and some of those nodes have children. Is it possible that when the node, or child is selected that the entire node including the children be selected?

View 5 RepliesI have a treeview and if I click on another control the hightlight disappears so I set the HideSelection to false and now the highlight row changes to a really light gray. Is there a way to have it still as dark blue. The reason being is because the user is clicking on a row in a grid and dropping it on the treeview and I need it to be clear that it will add it to the selected node which needs to be clear.
View 3 RepliesDoes anyone know if there is a way of populating a treeview from active directory so that it can do the following:Loads a list of servers --> Double Click the Server(Expand) --> Then i can select users --> then the department they are in --> then select the user so i can manage the user. i.e change there password[code]
