I need to add a menu item in the MDI form which will display the list of all the open child forms. In VB 6.0 when we create menu, there was a option of setting this option whether this menu is a Window list or not. Could anybody tell how can I set a Menu item to Window list so that in runtime it automatically populates itself with the list of open child windows. I am new in VB.Net 2005. Please Help.
Thanks in Advance.

Please send me vb.net code to check and uncheck nodes in treeview with multiple root nodes, subnodes

don't just ask for code
the right course of action is:
1 try to write it yourself
2 if 1 fails do a google search
3 if 2 fails ask here with you'r code from point 1 and specification where things go wrong
to help you on you'r way
loop thru the nodes in treeview
check the node
inside loop1 loop thru the nodes of that node
check the subnode
repeat loop2 for the subnodes
you will need to do this in a recursive methode
maybe this article could help (haven't looked at it for more than 1 min so can't be shure)

It is rude to demand people just send you code for solving a problem. Try solving it yourself, then when stumped, ask for help.

I want to put a Label or a Picture Box on a MDI Form, which can display some information or display a picture on the MDI form. If I put a label or picture box on the MDI form then, it gets displayed on the top of all child forms. How to display it on the background like the BackgroundImage property of the MDI form. Please Help...
Thanks in Advance.

You can't - that's what a MDI-form is for. In this case you can get around the issue by painting your own background image (with the image from the PictureBox / text from the Label) and displaying this.
Normaly if you want some information shown on the MDI - form you add a StatusBar or ToolBar

Thanks CKing, How can I put some information that frequently changes ?

Just use a StatusBar - most users are used  to this kind of visual information.

Hi everyone ,
I'm using vb.net 2003 (window application).
I have 2 textbox and want to add these 2 text into datagrid. But when i click "Add" Button for the 1st time, no problem. But after i click the 2 times, it replaced with the 1st row. But what i want is to add them into 2nd or subsequent rows depending on how many times i click 'Add' button.The 1st row remain.
Here i attach with my codes. I hope someone can hint me where is my mistake.
Thanks in advanced.
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd3.Click
Dim Table1 As DataTable
Table1 = New DataTable("LotNumber")
Dim Row As DataRow
Try
Dim HBarCode As DataColumn = New DataColumn("HBarCode")
HBarCode.DataType = System.Type.GetType("System.String")
Table1.Columns.Add(HBarCode)
Dim EMIBarCode As DataColumn = New DataColumn("EMIBarCode")
EMIBarCode.DataType = System.Type.GetType("System.String")
Table1.Columns.Add(EMIBarCode)
Row = Table1.NewRow()
Row.Item("HBarCode") = Me.txtHBarCode.Text
Row.Item("EMIBarCode") = Me.txtEMIBarCode.Text
Table1.Rows.Add(Row)
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
Dim ds As New DataSet
ds = New DataSet
ds.Tables.Add(Table1)
dgResult.SetDataBinding(ds, "LotNumber")
End Sub
thanks, eunice

Ok - the problem is that you allways create a new DataTable whenever you click add.
Put the section with the creation of the datatable / dataset to Form_Load or some other initialiser (you only want to call this once or when you need a clean DataTable) (Set the DataTable to be a private member of your class for access)
So you should get:
<br />
<br />
private myTable as DataTable = nothing<br />
<br />
public Sub InitGrid()<br />
<br />
myTable = New DataTable("LotNumber")<br />
Dim HBarCode As DataColumn = New DataColumn("HBarCode")<br />
HBarCode.DataType = System.Type.GetType("System.String")<br />
myTable .Columns.Add(HBarCode)<br />
<br />
Dim EMIBarCode As DataColumn = New DataColumn("EMIBarCode")<br />
EMIBarCode.DataType = System.Type.GetType("System.String")<br />
myTable .Columns.Add(EMIBarCode)<br />
<br />
Dim ds As New DataSet<br />
ds = New DataSet<br />
ds.Tables.Add(myTable)<br />
dgResult.SetDataBinding(ds, "LotNumber")<br />
<br />
end sub<br />
<br />
and
<br />
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd3.Click<br />
<br />
if myTable is nothing then InitGrid()<br />
<br />
Dim Row As DataRow<br />
<br />
Try<br />
<br />
Row = myTable.NewRow()<br />
Row.Item("HBarCode") = Me.txtHBarCode.Text<br />
Row.Item("EMIBarCode") = Me.txtEMIBarCode.Text<br />
myTable.Rows.Add(Row)<br />
<br />
Catch ex As Exception<br />
MessageBox.Show(ex.Message)<br />
End Try<br />
<br />
dgResult.Update()<br />
End Sub <br />
<br />

This is a SQL statement that is witten in Access for parameter search with wildcard
...
WHERE (((SLUŽBA.Priimek) Like "*" & [Search text] & "*"));
why doesn't it work in a Visual Basic Querry? I write the same expression in Function field and it doesn't work. Any suggestions?
Thanks.

|

In SQL - sytax this becomse something like
WHERE (SLUŽBA.Priimek LIKE %[Search text]%)
(% <=> * and no &)

Well, hard to understand what you mean by a 'Visual Basic Querry', but if you're building a string, you need to deal with how to represnt quotes for a start.

hi guys
i am running dotnet 2 exe file from network but it doest not run on my system , it says something
security like exception, but if i make my intrantet setting from dotnet framework2 configuration to gullytrusted it runs fine, but in this way i will have to make this setting on individual system, how to i do avoid from this issue,is there any that dotnet bypass the security or we can run our exe on tuntime in the fully trusted zone, thanks in advance
hello

First: there is no workaround IN code (that's what CAS is for)
As you said yourself: you either have to put the folder in the trusted zone / put the assembly in there or get some company policies for this task. However you will need to set these settings on ever client.
Of course if you copy the exe to local disks - say with a batch file before starting ...

Hi, I just want to know if it would be advised to put the following at the end of this code:
Set objFSO = CreateObject("Scripting.FileSystemObject")<br />
Set objOutFile = objFSO.OpenTextFile("\\jhbtest01\e$\SARS\Script\FileWithFilePath\FileNameFormA.txt", 2, True)<br />
strLine = FileName<br />
objOutFile.WriteLine strLine
Should i add this at the end:
objOutFile.Close AND is this the right way of doing the close section??? (it is working without it but i get error... so it works the first time round but fails second time round... without me seeing the error.)...
Oh yeah... this bit of code is in a javascript file that i call through VB.Net using the Shell()

Yeah, that would probably be a good idea.

This is probably because you didn't close the file and are trying to open it again.
Support123 wrote: this bit of code is in a javascript file
No, it's not. This is code snippet you posted is VBScript.

sorry about that... i was thinking one thing and writing another. I had a java question too (i am working on a ssis project and asp.net project so i messed up the question).
i appologize and thank you for the info. I will add the objOutFile.Close() section to the VBSript. (i dont know what the error is exactly... it is not displaying anything of use... it is saying that i have issues in one of my script files (vb.net) in the ssis package but it is working fine through visual studio... Only a problem when it is ran through a job in sql, so i thought that maybe the VBScript needed to be tweeked a bit.)
I will test to see if it works.
Thank you for your time.

Hi,
I'm developing a network application for a windows CE 5.0 device.
I need to visit a certain http:// url to process a php script. I have tried using process.start but that doesn't work.
So i'm using a webBrowser control to do the job.
The device is hooked to a usb cable on activeSync sharing the PC's internet connection. The connection works. ( I tried tracert somesite.com and it returned 30 hops.)
I'm using this code:
Dim uri As New System.Uri("http://www.somesite.hr/subfolder/index.php")
WebBrowser.Navigate(uri)
This code is on a button's click event. ( it works the same way on .net framework 2.0 but not the compact)
I keep clicking, and the code executes but the web browser is empty, nothing happens.
Any ideas?
Thank you!
