Hello everyone,
I am working on a module that involves querying from a .csv file in VB6. The problem that I am facing is with the Date/Time datatype. I have to compare the dates but it is being converted by the driver into text data type when the column is retrieved due to which the comparison cannot be made very accurately.
I want to know if there is some way by means of which I can convert the datatype of the column obtained from the .csv file from text to Date/Time. Something like the toChar function in PL/SQL would be usefull.
I am facing the same data type conversion problem when I tried to import the data into an Access table and tried to query it.
Please send a response to this as early as possible.
I need it urgently.
Thanks
Sathya

Try using CDate() to convert text to a date data type.
Dim t As String
Dim d As Date
t = "January 23, 2004 7:45 AM"
d = CDate(t)
MsgBox d

Hi friends, Can any body tell me that how can I disable some rows in the datagrid. The exact requirement is that in the datatable I have 5 rows (For example) and it has 2 columns. One of those columns is boolean. And all those rows will be disabled who has that boolean value true. Waiting for ur replies.

You can get the list of machines that are both in the Directory and logged into Active Directory using the methods described here[^].
There is an introduction to using the Active Directory objects in VB here[^].

I am attempting to write a script using ms ie as an object, and controlling a sequence of interactions with the site without having to physically move the mouse around and click and type into message boxes or select boxes. This is all from the client side, of course.
So far, I have code that will alow me to open an explorer window at the selected http site and click on any button I want to. But I have not found a way to enter text, or select from a list box.
Does anyone here know how to do this? I am beginning to think that it is not even possible after searching for hours on the net.
Is there a way to simulate key presses?
Where can I find a complete referance to the ie procedures?

When you tell the IE Object to Navigate to a web page, it will fire a DocumentComplete (I Think!) event to let you know that the enitre page has been retrieved. In your event handler, you can get a reference to the Document using something like this:
Dim objDocument as Document
Set objDocument = objIEBrowser.Document
(Someone feel free to correct me if I'm wrong!)
From there, you can use the Document object to find the control that you want in its Elements collection. You can then modify the text you want, then you call the Click method of the submit button, which you will also find in the Elements collection somewhere.
You can find the complete document on the Document object model here[^].

Hi,
i should use a Component in VBScript or JScript that has a Function with an out parameter.
in VB I can use the Component like this:
Dim myComponent As Component<br />
Set myComponent = New Component<br />
Dim res As Long<br />
Call myComponent.MyFunction(res, "some String", 1, 2, "another Text")<br />
If res <> 0 Then MsgBox ("Error while executing MyFunction")
how can I write the VBScript of JScript code that the res variable is passed by reference and not by value, so i can check the value afterwards?

Last I checked, VBScript doesn't support passing by reference. You can only pass by value.
EDIT:
My bad! Script 5.6 supports passing by reference. Checking into the problem though...

OK. When you write your component, all that you need to do is add ByRef to the declaration where 'res' is going to get passed in:
Public Sub MyFunction(ByRef var1 As Integer, var2 As String, var3 As Integer)
I verified that this does work between a VB6 ActiveX control and VBScript on Windows Script 5.6.

The Problem is:
The Component was built with Visual C++ (ATL). The Parameter is declarated as [out] in the type library file, but I sgould be able to tell this the VBScript/JScript.
Wit VBScript I get an compile error 'Type mismatch', with JScript it compiles but the Variable is not changed through the Component.
I left this problem behind with writing a small C++ App that i call from the Script, but thanks for your help.
Of course, if you have some idea, your input is still very welcome.

I have a very annoying problem, with which I NEED HELP DESPERATELY!!
It smells like a bug to me, but I'm not sure.
SITUATION
This description is a very much simplified version of the real situation.
I have the following class structure:
ASSEMBLY ATools
References: None
Namespace : Tools
Classes : CToolClass
ASSEMBLY ABaseClasses
References: ATools
Namespace : BaseClasses
Classes : CBase1, CBase2
ASSEMBLY ASubClasses
References: ABaseClasses, ATools
Namespace : SubClasses
Classes : CSub1 Inherits BaseClasses.CBase1
ASSEMBLY AWebClasses
References: ABaseClasses, ASubClasses, ATools
NameSpace : WebClasses
Classes : CWebClass Inherits System.Web.Services.WebService
Both baseclasses have a method with signature:
Public Sub Init(ByVal parm As Tools.CToolClass)
The webclass has a method, which SHOULD look something like this:
<webmethod> _
Public Function MyWebMethod() As String
Dim oObj1 As SubClasses.CSub1 = New SubClasses.CSub1
Dim oObj2 As BaseClasses.CBase2 = New BaseClasses.CBase2
Dim oTool As Tools.CToolClass = New Tools.CToolClass
...
oObj1.Init(oTool)
oObj2.Init(oTool)
...
Return ...
End Function
PROBLEMS
The following problems occur in MyWebMethod:
1.
In the above situation, I get an error on the line "Dim oObj1 As SubClasses...": "Reference required to assembly 'ABaseClasses' containing the type 'ABaseClasses.CBase1'. Add one to your project.".
As you can see, the reference is already there.
To solve this problem for the time being, I copied CBase1 into ASubClasses and made CSub1 inherit SubClasses.CBase1.
2.
After the changes made as described in 1., another error of the same type appears: "Reference required to assembly 'ATools' containing the type 'ATools.CToolClass'. Add one to your project.". However, this error appears only on the line "oObj1.Init(oTool)", which references a subclass. It does not appear on the line "oObj2.Init(oTool)", which references a baseclass.
And again, the reference is already there.
QUESTION
1. What causes the problem?
2. What can I do to solve it?
Obviously, copying all my classes into one single assembly is not what I want. So, what should I do?
PLEASE HELP ME! Thanx a lot!

Hi,
I am using System.Threading namespace as I want to continuously fetch some data from the server and give some notification to the user. I am using SQlDataAdapter,dataset and sqlcommand to fill multiple tables in the dataset. Along with this I also want the user to do his normal work on the software. At that time if he performs another operation where another Sqldataadapter,dataset and sqlcommand is used it gives error while setting commandtext property in the sqlcommand. the error is "Sql Command is busy fetching data"
How to overcome this error?
Thanks Tasnim
