Hi,

FontFamily.GetFamilies() returns an array of type FontFamily
that class has a Name property.
it also has a ToString() method but that is not guaranteed to return the name
that you want !

You'll have to wait for the user to pick the font, then repopulate a size combobox depending on the font. Not all fonts are the same. Some are bitmap fonts that have various sizes built into the file they come from, others are like TrueType fonts that are outline fonts and are only stored in the font file in one or two sizes. Those outlines are then scaled to any size the user wishes.

Alternativly just use the FontDialog provided in the System.Windows.Forms namespace to let the user select the font, size, style and everything. That way all the hard work is done for you by Microsoft.

If you have knowledge, let others light their candles at it.

Emailing data

i am writing a program where the user enters data into a windows form
and then saves that data to a database, i then want the user to click
a button that sends an email to there department manager with a summary
of the data entered.

the question is what would be the best way to approach this? i was
thinking of either producing a report and sending that as an attachment
or somehow have the data entered in to the body of the email.

any suggestions please

That's entirely up to you. It depends on what the use wants to see. If they want to see a report, you can pick whatever format you want for it, that exports a file anyway, like PDF, and use one of the publicly available PDF writersto print to a file and attach it to the email, or you can send it as formatted text in the body of the email. It's entirely up to you.

I personally, like to see nice emails with a report...

I am trying to insert record into and SQL Server 2000 database and I keep getting the following error:

Cannot insert the value NULL into column 'ItemID', table 'RAM.dbo.Item_JS'; column does not allow nulls. INSERT fails.
The statement has been terminated.

The column ItemID is set to autonumber in the db. Here is my code:

Dim myConnString As String = "Data Source=********;Initial Catalog=******;User ID=*****;Password=*****;"<br />
<br />
Dim myInsertQuery As String = "INSERT INTO Item_JS (ItemPartNumber, ItemSourceCode,       ItemSupercede, ItemCost, ItemName, ItemListPrice, ItemLastUpdateDT, ItemStatus, ItemCreationDt, CompanyID, StoreID, BrandID, PackageID) VALUES('" & Trim(partnumber) & "', '" & Trim(sourcecode) & "', '" & Trim(supercede) & "', CONVERT(MONEY,'" & cost & "'), '" & Trim(itemname) & "', CONVERT(MONEY,'" & listprice & "'), '" & Trim(lastupdateDt) & "', '" & Trim(status) & "', '" & Trim(insertdate) & "', '" & Trim(companyID) & "', '" & Trim(storeID) & "', '" & Trim(brandID) & "', '" & Trim(packageID) & "'" & ")"<br />
<br />
Dim myConnection As New SqlConnection(myConnString)<br />
myConnection.Open()<br />
Dim myCommand As New SqlCommand(myInsertQuery, myConnection)<br />
myCommand.ExecuteNonQuery()<br />
myConnection.Close()

Any Ideas?

Have you tried inserting a value in the ItemID field? It is supposed to autonumber, but, from your comments, it doesn't appear to.

For what its worth, I DETEST autonumber... it has and is causing me to get heartburn... rather than autonumber, use a transaction or something to get the last value used and increment it for your insert.

The Scope of the Adapter in the Following code

Am using vb.net 2003, i was used to the drag and drop style of adding adapter's in my project, now am going down to code everything, when i create a data, adapter, i code them behind. before when i drag and drop the adapter in the form, i could call that adapter in my Button. i have the Following code that i have wrote in my form load

Dim strconnection As String = "workstation id=5875-049;packet size=4096;user id= sde; Password=topology;data source= SGIICORNETGS01;persist security info=False;initial catalog=Tshwane_Valuations"
        Dim cn As SqlConnection = New SqlConnection(strconnection)
        cn.Open()
        'set up data adapter 
        Dim strSql As String = _
          "select Actual_Extent,Attrib_code,Lis_key,Func_key,Density," _
          & "New_Net_Usable_Extent,New_Total_Land_Factor,New_AdJ_Extent_1,New_Points_1," _
          & "New_ADJ_Extent_2, New_Points_2, LS_Prediction, LS_Confidence,LS_TYPE from Property_Mass "
        Dim da As SqlDataAdapter = New SqlDataAdapter(strSql, cn)

        'load the Data set

        Dim ds As DataSet = New DataSet
        da.Fill(ds, "Property_Mass")

        'set up data Adapter Object
       


        Dim strErrorMsg As String
        Dim strerror As System.Data.SqlClient.SqlError

        'set up the data soruce 
        
        strSql = _
        "select Property_Mass.Actual_Extent,Property_Mass.Attrib_code,Property_Mass.Lis_key,Property_Mass.Func_key,Property_Mass.Density," _
       & " Property_Mass.New_Net_Usable_Extent,Property_Mass.New_Total_Land_Factor,Property_Mass.New_AdJ_Extent_1, Property_Mass.New_Points_1," _
       & " Property_Mass.New_ADJ_Extent_2, Property_Mass.New_Points_2, Property_Mass.LS_Prediction, Property_Mass.LS_Confidence, Property_Mass.LS_TYPE," _
       & " Property_Summary.Purchase_Date, Property_Summary.Purchase_Price" _
        & " from Property_Mass, Property_Summary" _
        & " where Property_Mass.Lis_key = Property_Summary.Lis_key"
        da = New SqlDataAdapter(strSql, cn)
        'load a Dataset 

        Try
            da.Fill(ds, "Property_Summary")
            '      BindingSource(bindingSource = New BindingSource)

            'Close the Connection
            cn.Close()

            'Create relations 
            ds.Relations.Add("Property_summary_Mass", _
            ds.Tables("Property_Mass").Columns("Lis_key"), _
            ds.Tables("Property_Summary").Columns("Lis_key"))

            'Bind the data set to the grid.
            'Assumes that Grid contains a reference to a 
            'system.windows.datagrid
            DataGrid2.SetDataBinding(ds, "Property_Mass")
            'sorting the Datagrid
            DataGrid2.AllowSorting = True


        Catch ExSQL As System.Data.SqlClient.SqlException
            '''All this will trap all data Problems and Network if available
            For Each strerror In ExSQL.Errors
            Next
            Select Case strerror.Number
                Case 17
                    strErrorMsg = "Missing server"
                Case 4060
                    strErrorMsg = "Missing database"
                Case 18456
                    strErrorMsg = "Missing user name or password"
                Case Else
                    strErrorMsg = strerror.Message
            End Select
            MessageBox.Show(strErrorMsg, "SQL Server Error: " & strerror.Number, MessageBoxButtons.OK, MessageBoxIcon.Error)

        Catch ExcpInvOp As System.InvalidOperationException

            MessageBox.Show("Close the connection first!", "Invalid Operation", MessageBoxButtons.OK, MessageBoxIcon.Error)

        Catch Excp As System.Exception ' generic exception handler

            MessageBox.Show(Excp.Message, "Unexpected Exception", MessageBoxButtons.OK, MessageBoxIcon.Error)
        End Try
    End Sub

This code is working well and it display my dataset results on load. So i have included a Button to Search for a certain Column,but now when i try to use "da" which is the adapter declared in Form load,trying to access it from the button i have placed in my form. it complains about declaration. i understand everything in a form load is Private and the buitton itself is private,

1) how can i declare the adapter and the connection objects to be on the same scope when you drag and drop them on the form?
2)And from my search, am searching from a Field that has (## ## ## ## ##) numbers in a string Field, and i have to rearch by retrieving the first four,i can do that in SQL by using substring, tell me how can i achieve this and display the data in the datagrid.?

The scope as you've written the code, is the life of the Form_Load sub. Anything you Dim in the Sub is destroyed when execution leaves the Sub.

You can't. Their code is created in different places.

I think you're asking about what the SQL SELECT would look like??

SELECT columns FROM table WHERE someColumn LIKE @Pattern

In your code, you'd add a SqlParameter object, with the parameters name @Pattern to the SqlCommand object this SQL is in and set it's value to something like "39 49 20 10 %". THe percent sign is the "wildcard" and will match anything else after the initial string.

move the toolbar in program

hi all

i need to move the toolbar on the form

will some one let me know how to do that

thnx

Tom Deketelaere31-Jul-07 1:46

31-Jul-07 1:46

I'm assuming you use a toolstrip for this

if so you can do this very easaly

just select the toolstrip and then in the tasks window (the little arrow on the upper right corner of the control or the gray area under the properties window) select 'embed in toolstripcontainer' then just put the toolstripcontainer dock property on fill.

after this the user can move the toolstrip around the form (all controls added to the form must be in the toolstripcontainer)

the 'gripstyle' property of the toolstrip has to be set to 'visible'

eyes200731-Jul-07 2:46

31-Jul-07 2:46

thnx for the help

but it not just working

i select the toolstrip and then select embed in toolstripcontainer this make a new container

then when i put the toolstripcontainer dock property to fill then it fills the whole form

i have
2 toolstrip
one ruler
one erichtextbox and
one statustrip

plz tell me what m i forgeting

MartyK200731-Jul-07 3:17

trying switching off docking
switchimg off auto size then move the tollstrip to where you wish it to be and then use the anchors.
This works with tools trips dont know about the containers though.

Hi all
Just need some advice and help with the issue of Threads..Just come over from VB6 and not to sure about this one..

I have an application which waits for HTTP requests which is the main process. Once a request is recieved a thread is started to do something..on the Main Form i have a status Textbox which i want to keep up to date with the HTTP requests and also when the thread has finished etc.

Please advise as to how i may achieve this

TIA

Since all Controls normally get created by the main thread (aka "GUI thread")
and should be handled only by the thread that created them (they are not
thread-safe), one needs a special technique to access them from another thread.

The Control class has some members to support this: the InvokeRequired property
and the Invoke() or BeginInvoke() methods. I suggest you read up on these;
examples are plenty on CodeProject. There is one in my Sokoban article (that's
in C# but the concept is exactly the same).
