I have a Parent form with multiples tables.
let's say a group box that display text from table1 and also
I have a comboBox binding to table1 inside this groupbox along with textboxes.
On addnew from the parent table, I want to click on individual AddNew button to load a child form where I can select the one record that I want to show back to the parent table. Hence the selected PK id from table1  will show in the comboBox along with its text.
Can anyone guide me and I will be greatly appreciated..
thanks

You need to hook a delegate between the child and the parent, so that you can call a method in the child form, and it runs a method in the parent form. There's plenty of articles on delegates around.

can u point me to some delegate articles since I don't know not much about delegates.
I reformulate my question...
I am using Vb.net and Sql express I have a Parent form with multiples tables for example table1, table2, etc. I have a group box that display textboxes from table1 and along a comboBox binding to table1 datasource. On Bindingaddnewitem on the parent form, I want to click on individual AddNew button to load a child form with table1 records where I can select the one record. I want to show this record back to the parent form. Hence the selected PK id of that particular record from table1 will show back in the comboBox on the parent form along with its text. I hope I make myself clear.. Can anyone give me an idea. if I use combox to select the record from table1, this can be huge. therefore I just want the one record from the child form which can be slected from a search or slelected or new added record. Can anyone guide me and I will be greatly appreciated..
Thanks

Why could you not just use a getter setter on the child form?

thanks for reply but have no idea what is a getter setter
|
|
|
|

You would want something like this on the child form.
Private iIntegerToBeSetGet As Integer = 0
Public Property iIntegerSetterGetter() As Integer
Get
Return iIntegerToBeSetGet
End Get
Set(ByVal value As Integer)
iIntegerToBeSetGet = value
End Set
End Property
and something like this in the parent form.
Dim objMyForm As New Form1
Dim i As Integer = objMyForm.iIntegerSetterGetter()
objMyForm.iIntegerSetterGetter = 12
Just use the value in the combobox that you want to show up on the parent form.

Thanks!
But on the child form, I have a datagridview and a search criteria. I do not have a combobox on the child form because try to avoid a huge list to select from..
I want to either search for a record or add a new record on the child form and then parse it back to the parent form..
Here is the scenario:
New Registration form
AddOffenderbutton will load offenderform (child form)to fill offenderlastname.text, offenderfirstname.text, offenderidentification.text, etc.. on the parent form(Registration form)
Hope I am bit clearer now..
Thanks a lot

I'm trying to write a utility that can compare a dataset to an existing SQL Server and then make changes to it via SMO
the problem i'm having currently is getting the indexes to be created properly.
dt is a table from the the .xsd dataset
TableToUpdate is the table i'm going to be making changes to.
VerifyTable is an exact copy of the table made at the same time TableToUpdate was created.
Private Function UpdateColumn(ByRef TableToUpdate As Microsoft.SqlServer.Management.Smo.Table, ByVal ColumnToAdd As System.Data.DataColumn, ByVal dt As System.Data.DataTable, ByVal VerifyTable As Microsoft.SqlServer.Management.Smo.Table) As Boolean<br />

col.Nullable = ColumnToAdd.AllowDBNull<br />
col.DataType = GetTypeOfData(ColumnToAdd)<br />
<br />
If Not ColumnToAdd.DefaultValue.Equals(DBNull.Value) Then<br />
col.AddDefaultConstraint("DF_" & col.Name)<br />
col.DefaultConstraint.Text = ColumnToAdd.DefaultValue.ToString<br />

This will show you how to load logon info for each table and then set the databases in in each report.
I have also included code on how to send parameters to the report.
<pre>Dim rdReport As New ReportDocument
Dim LogInfo As CrystalDecisions.Shared.TableLogOnInfo
rdReport.Load("\\sysdatacenter\Public\Quality_Control\Reporting\" & reportName & ".rpt")
Dim crConnectionInfo As New CrystalDecisions.Shared.ConnectionInfo()
With crConnectionInfo
.ServerName = DataServer.Server
.DatabaseName = DataServer.Database
.UserID = DataServer.UserName
.Password = DataServer.Password
.IntegratedSecurity = DataServer.Security
End With
LogInfo = New CrystalDecisions.Shared.TableLogOnInfo
LogInfo.ConnectionInfo = crConnectionInfo
Dim crTable As Table
For i As Integer = 0 To rdReport.Subreports.Count - 1
For Each crTable In rdReport.Subreports(i).Database.Tables
crTable.ApplyLogOnInfo(LogInfo)
Next crTable
Next
For Each crTable In rdReport.Database.Tables
crTable.ApplyLogOnInfo(LogInfo)
Next
rdReport.Subreports("rptSettings").SetDataSource(dsReport.Tables("tblJobSettings"))
rdReport.SetDataSource(dsReport.Tables("tblSerialNumbers"))
For l As Integer = 0 To rdReport.ParameterFields.Count - 1
Select Case rdReport.ParameterFields(l).Name
Case "Company_Name"
rdReport.SetParameterValue("Company_Name", frmMain.ProgramDefault.CompanyName)
Case "Company_Address1"
rdReport.SetParameterValue("Company_Address1", frmMain.ProgramDefault.CompanyAddress1)
Case "Company_Address2"
rdReport.SetParameterValue("Company_Address2", frmMain.ProgramDefault.CompanyAddress2)
Case "Company_City"
rdReport.SetParameterValue("Company_City", frmMain.ProgramDefault.CompanyCity)
Case "Company_State"
rdReport.SetParameterValue("Company_State", frmMain.ProgramDefault.CompanyState)
Case "Company_Zip"
rdReport.SetParameterValue("Company_Zip", frmMain.ProgramDefault.CompanyZip)
Case "Company_Phone"
rdReport.SetParameterValue("Company_Phone", frmMain.ProgramDefault.CompanyPhone)
Case "Company_Fax"
rdReport.SetParameterValue("Company_Fax", frmMain.ProgramDefault.CompanyFax)
Case "Company_Web"
rdReport.SetParameterValue("Company_Web", frmMain.ProgramDefault.CompanyWeb)
End Select
Next
Me.crViewer.ReportSource = rdReport
Me.Cursor = Cursors.Default

I am currently writing an application in VB.Net that requires me to deal with TIFF-JPEG Compression format, I have done some research on this and as far as I know GDI+ does not support this format. Does anyone know if there is a way around this problem either with or without a third party plug-in? Ideally I would like to avoid using third party plug-in if possible, but if not, can anyone recommend me a good third party plug-in that support this. I need to be able to do the follwoing:
1. Convert the TIFF-JPEG compression file into another format like bitmap or JPEG that GDI+ support.
2. The user will then be able to do whatever editing they need to do on the image (I have handled this part already).
3. Convert the edited image back into TIFF with JPEG compression format.
Any help or advise would be much appreciated, thanks in advance.

You do not have a choice. You must use a third party image library (not a plugin) to handle these types of images. GDI+ does not support them.
|
|
|
|

Agreed with Dave and the 3rd party approach would probably be the easiest to implement.
You might be able to "strip logic" out of a free program that has this functionality already. Maybe check into Paint.Net (not sure if the prog. is open source), but something like that. Check CodePlex as well.

Hi,
I have created a table in ms-access using VB.NET like below.
ADOXtable.Name = "ACN_CHARX_INSTANCE"
ADOXtable.Columns.Append("LOGICAL_DB_NAME", ADOX.DataTypeEnum.adVarWChar, 32)
ADOXtable.Columns.Append("DIM_NAME", ADOX.DataTypeEnum.adVarWChar, 32)
ADOXtable.Columns.Append("CHARX_NAME", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_TABLE", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_VALUE_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("VALUES_UNIQUE", ADOX.DataTypeEnum.adInteger)
ADOXtable.Columns.Append("CHARX_ORDER_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("CHARX_ORDER", ADOX.DataTypeEnum.adInteger)
ADOXtable.Columns.Append("CHARX_NUMERIC_COL", ADOX.DataTypeEnum.adVarWChar, 128)
ADOXtable.Columns.Append("BITMAP_COL", ADOX.DataTypeEnum.adVarWChar, 128)
cat.Tables.Append(ADOXtable)
After that i gave a primary key like below,
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "LOGICAL_DB_NAME")
But now i want to add composite key for this table..I added the code like the below..
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "LOGICAL_DB_NAME", "DIM_NAME", "CHARX_NAME")
But after executing this code, the key is allocated for Logical_Db_name field only.
Please share your ideas about how to create composite key using VB.NET...
Thanks,
Sivakumar.M.

Instead of putting all the column names in one line, I think you have to call Append again with the 2nd column, and again for the 3rd that you want to add as part of the key.
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "LOGICAL_DB_NAME")
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "DIM_NAME")
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "CHARX_NAME")

Thanks for your reply...if i give like below as u advised,
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "LOGICAL_DB_NAME")
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "DIM_NAME")
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "CHARX_NAME")
ADOXtable.Keys.Append("PrimaryKey", ADOX.KeyTypeEnum.adKeyPrimary, "CHARX_TABLE")
Exception raised...

Well, I didn't say I tested it. I said I think you may have to do something like that. Try reading the documentation on ADOX's Key.Append method. You may have to supply other information to the Append method, like foreign table names and columns.
|
|
|
|
|
Something like this?
key1 = New ADOX.key
key1.Name = "PrimaryKey"
key1.Type = ADOX.KeyTypeEnum.adKeyPrimary
key1.Columns.Append "LOGICAL_DB_NAME"
key1.Columns.Append "DIM_NAME"
key1.Columns.Append "CHARX_NAME"
ADOXtable.Keys.Append key1
Note the similarity with yesterdays index question - have a look at the ADOX object library.

Hi all,
I have an application in Visual Basic 6.0, which spools text to a text file and then prints. After printing file will be deleted. But here, I couldn't know printer status. Is printing over or still printing...I couldn't know. If I know, I wont delete the file. If that is single file, then I can adjust, but continually 10 files will be printed.
All I want to know the status of the Printer...Please help me out.

Why are you using VB6 ? It really sucks. And, it's unsupported. If you want VB6 help, you should put it in the subject line, so you only attract people who have been developing long enough to remember what that was.

No, no. It's "people who are still young enough to remember what that was."
