Do all your dll's implement an interface? I am not sure a way of doing this in VB 6.0
In VB.NET you can use reflection.

Thanks. I found how to do this. we can use the "CallByName" in VB6. the Method Signature is as follows.
-----------------------------------------------------------------------------------------
CallByName(Object as Object,ProcName as String,CallType as VbCallType,Args() as Variant)
where CallType can be
VbLet
VbGet
VbMethod
VbSet
-----------------------------------------------------------------------------------------

i want to pass the query string in javascript function hen i use the following code :-
Dim popupScript As String = "" + "window.open('popup.aspx?ID=" + id + "', 'CustomPopUp', " + "'width=550, height=550, menubar=no, resizable=no')" + ""
Page.RegisterStartupScript("PopupScript", popupScript)
then it give me the following error:-
ERROR - "Conversion from string "wi" to type 'Double' is not valid."
please give me the solution
|
|
|
|
|
My guess would be that id is declared as a double?

mr_12345 is right. Since you're using the addition operator and you have a number in the expression, you're actually trying to add a string to a Double. Use the string concantenation operator, "&" instead. Better yet, minimize using it as much as possible.
Dim popupScript As String = "<script language='javascript'>window.open('popup.aspx?ID=" & _
id.ToString() & "', 'CustomPopUp', 'width=550, height=550, menubar=no, resizable=no')</script>"

You have 2 choices:
select case FormToDisplay
case "Form1"
dim form as new Form1
case "Form2"
dim form as new From2
case "Form3"
dim form as new Form3
end case
form.Show
or
Look at using reflection.

Hi there ,
Can anyone tell me what apppath does? Can I give apppath to my database in VB 6.0. If yes, then what will happen if I change my location of the database from one server to another, and what should I do if in future I want to change my path of the database?
Plz help me out.
Thanx & Regards.

AppPath gives you the directory path of your executable.
If using VB6, you can put your connection string in an ini file or the registry. If using .Net then you can put it in the app.config file or the registry. This way you can easily move your database without recompiling your code.

Hi,
Sorry but I don't know ur name. First I would like to thank u for ur quik response.But I would b requiring some more help.Plz help.
I would like to know in wich ini file should I save the database path,Will I need to give additional attributes of the database like USERID,PASSWORD,LOCKTYPE in that file, and How should I execute that file from the application?
Thanx & Regards.

You can create your own ini file. Example appliationName.ini. I would place this file in the same directory as your executable.
As far as placing the user name and password in this file, I don't recommend it (unless you perform some kind of encryption on the password).
Are you using one user id to connect to your database or will everyone that logs in have a different user name and password? What kind of database are you trying to connect to?
As for reading and writing to an ini file look at the following link or do a search on google

Need some direction; through vb.net can you use DDE links directly? I know that they are used in Excel. Where can I go to get information on working with FIX/API? Can you use Active-X controls in vb.net? Just a web site or book. Thank You

machman1 wrote: through vb.net can you use DDE links directly
No. There is no support for DDE in the .NET Framework. YOu'll have to P/Invoke the appropriate Win32 functions to use DDE.
machman1 wrote: Where can I go to get information on working with FIX/API
Google search results[^].
machman1 wrote: Can you use Active-X controls in vb.net
Yes. Just add it to the ToolBox. Right click in the ToolBox, then pick Add/Remove Items... Find your ActiveX control on the COM tab and you'll be all set to drop it on your form.

Hi.
is there anyway I can track when user opens a file? I don't need to know creation, modification, and deletion because I'm already using FileSystemWatcher for that. I used LastAccess filter but it seems doesn't work or maybe it does but I cannot see it. All I need to know that user opened the file and let's say reads it.
My program writes all events to the flat file so I can see all events raised.
Thank you in advanced.
Alex.

There is no event for this. You'd have to hook the file system, just like FileMon does.

g = Graphics.FromImage(bmp)
g.TranslateTransform(pb.Width / 2, pb.Height / 2)
g.DrawEllipse(New Pen(color.MediumTurquoise, 1), 0, 0, 2, 2)
g.DrawRectangle(New Pen(color.FromArgb(0, 0, 0)), 0, 0, 100, 100)
g.DrawEllipse(New Pen(Color.Red, 1), 0, 0, 100, 100)
cntnr = g.BeginContainer(rect1, rect2, GraphicsUnit.Pixel)
g.TranslateTransform(20, 20)
g.Clear(BackColor)
g.DrawRectangle(New Pen(Color.FromArgb(255, 255, 255)), 0, 0, 100, 100)
g.EndContainer(cntnr)
g.DrawLine(New Pen(Color.Blue, 1), 0, 0, 200, 200)
I am confused by losing all of my scratches before the "BeginContainer" because of the "Clear(BackColor)",why?

Hi,
Ich suche nun schon eine längere Zeit, um den aktiven Node eines Windows Clusters auszulesen. Ein Scope zum WMI Objekt konnte ich öffnen, nur kann ich die entsprechenden Informationen nicht auslesen.
Dim clustName As New String("myCluster")
Dim clustGrpRes As New String("myResGrp")
Dim conOpt As New ConnectionOptions
conOpt.Username = "domain\myUsrName"
conOpt.Password = "myPassword"
Dim mgmScope As ManagementScope
Dim mgmPath As ManagementPath
Dim mgmObj As ManagementObject
mgmScope = New ManagementScope("\\" & clustName & "\root\mscluster", conOpt)
mgmPath = New ManagementPath("MSCluster_ResourceGroup.Name='" & clustGrpRes & "'")
mgmObj = New ManagementObject(mgmScope, mgmPath, Nothing)
OS auf dem die Applikation ausgeführt wird: Windows Server 2k3 Standard Edition
OS des Clusters: Win Server 2k3 Enterprise Edition
Kennst Du eine Möglichkeit, wie ich an die benötigten Informationen gelange?
Danke für Deine Bemühungen

You do realize this is an English speaking board, right?
Babel fished:
----------------------------8<----------------------------
I look for a longer time now already, in order to select the active Node of a Windows cluster. A Scope to the WMI I could open object, only I cannot pick the appropriate information out.
Dim clustName As New String("myCluster")
Dim clustGrpRes As New String("myResGrp")
Dim conOpt As New ConnectionOptions
conOpt.Username = "domain\myUsrName"
conOpt.Password = "myPassword"
Dim mgmScope As ManagementScope
Dim mgmPath As ManagementPath
Dim mgmObj As ManagementObject
mgmScope = New ManagementScope("\\" & clustName & "\root\mscluster", conOpt)
mgmPath = New ManagementPath("MSCluster_ResourceGroup.Name='" & clustGrpRes & "'")
mgmObj = New ManagementObject(mgmScope, mgmPath, Nothing)
OS on that is implemented the application: Windows Server 2k3 Standard Edition
OS of the cluster: Win Server 2k3 Enterprise Edition
Do you know a possibility, how I arrive at the necessary information?
Thanks for your efforts
----------------------------8<----------------------------
I don't have a cluster to test on but you might be looking to execute a WMI query like:
SELECT Status From MSCluster_ResourceGroup WHERE Name='clusterGroup'
