how do I create/show modal form using the following code?

Posted By:      Posted Date: September 06, 2010    Points: 0   Category :Windows Application
The text contained in a .txt file loaded with the following code doesn't show up in the RichTextBox control on a separate form which has been instantiated and launches sucessfully.  Why don't the contents of the .txt file show up in the RichTextBoxControl on the instantiated form?  Thank you for ideas! private void ToolStripMenuItemOpenAlarmHistory_Click(object sender, EventArgs e) { OpenFileDialog openFile1 = new OpenFileDialog(); FormAlarmHistory_Loaded_Into_RichTextBox formAlarmHistory; openFile1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"; if(openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK && openFile1.FileName.Length > 0) { using (formAlarmHistory = new FormAlarmHistoryLoadedIntoRichtTextBox()) { dialogResult = formAlarmHistory.ShowDialog(); if (dialogResult == DialogResult.OK) { formAlarmHistory.richTextBoxPrintCtrlForLoadedAlarmHistory.LoadFile(openFile1.FileName); } } } }

create a form to create an ascx page and code behind for it

Is is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.I don't know if I'm describing it very well, maybe someone could point me in the right direction.

Code Name Avalon: Create Real Apps Using New Code and Markup Model


The presentation subsystem in the next version of Windows, code-named "Longhorn," offers powerful new capabilities to developers. This subsystem, code-named "Avalon," allows developers to take advantage of its capabilities through a new markup language code-named "XAML." In addition, modern object-oriented programming languages such as C# and Visual Basic .NET can be used to tie everything together. Because most applications written to Avalon will probably be a mix of XAML and programming code, this article discusses XAML tags used to control page layout along with the procedural code written to respond to events.

Create databound nested ajax toolkit accordion programatically(In code Behind)


Can anyone guide me in the right direction or give an example of How I would accomplish this?

I have a xmldatasource.. In a nutshell at what point in my code do I need to create a new accordion? does it need to be

    Implements System.Web.UI.ITemplate

    Dim templateType As String

    Sub New(ByVal type As String)
        templateType = type
    End Sub

        Dim ph As New PlaceHolder()

        Select Case (templateType)
            Case "Header"
                Dim myLabel As Label = New Label()
                myLabel.Text = "Test"
            Case "Content"
                ph.Controls.Add(New LiteralControl("<p>hello</p>"))
        End Select

InfoPath form checked out so 'on create' workflow not being started


Hi all,


I have found a couple of threads asking for advice on how to check in an InfoPath form when it’s saved or submitted to a forms library. The reason for doing this is so a workflow can start based on a new item being created in that library, and so it doesn’t just sit there with a “Starting” status.


The answers I have found contradict each other:

·         You have to do it with a workflow.  This can be done easily with SharePoint Designer if that's an option for you. Source:

Programmatically create an InfoPath form


I'm programmatically creating an InfoPath form using this article: http://www.bizsupportonline.net/infopath2007/programmatically-create-infopath-form-console-app.htm.


Everything works well up to 29 fields (my:field1 ... my:field29). After that it runs without an error and posts a form to the library however the icon does not switch to an infopath icon and the filename stays blanks. I don't believe this field specific, it seems to be happening when I use any 29 to 30 fields so I'm thinking its a memory issue with the stream reader.

Has anybody every had this issue before, is there a way to fix this?

Extracting Infopath form templates (with code behind) from a farm



I am in the middle of a migration of MOSS 2007 on server 2003 R2 to server 2008 r2, to be in the position to migrate to SP 2010. I am trying to extract form templates (with code-behind) from the old farm to the new farm. I did not set this farm up myself, so I would have copies of everything that was deployed to the farm, but now I don't. I have tried grabbing the .xsn from the Form Templates form library, and the form comes over, but no code behind, it says, The VB or C# project for this form template cannot be found. I have also tried extracting the solution files, and changing the file ext to .cab and opening the file up, only to find nothing very useful.

I need to extract and open the code up because I believe one of the forms that sends emails dynamically, is pointing to an old exchange server, because the emails are not getting through, and the exchange server was recently changed.

Any ideas would be much appreciated.

create a secure new item form



i hope i can explain this the right way.

i'm using sharepoint services 3.0 and sharepoint designer

i have to create this senario:

the employee need to fill in a new item form to request for absence or vacation days.

for this i use the Absence and Vacation Schedule template. a good one!

but the thin is i have to modify the "new item form" that when the user open the "new item form" it has to get the id from the employe and join it to the id of his manager. so when the employee fill in the form it can only go to the employe his manager for approval. the purpose for this senario is that the employee dont get a chance to send his request to another manager or to the HR department without an aproval.

is there a workflow for it. or how can i join the employee id with the manager id?

and how can i create a web part that counts the vacation days of an employe and also display how many days he has left so he knows how many days he can request for?

hope some1 can help me with this
