View 1 RepliesVisual Studio Macro - Read First X Lines Instead Of Entire Document?
Jul 5, 2010I've got a macro that updates a copyright header with the most recent edit date.
The problem I have is that the macro currently reads through the entire file rather than just the first 6 lines (which is all it needs).
Is there a way to get the Macro to only read the first "X" lines rather than the entire file?
Private selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection
Private Sub UpdateCopyrightHeader()
selection.StartOfDocument()
selection.EndOfDocument(True)
Dim content As String = selection.Text
Dim result = System.Text.RegularExpressions.Regex.Replace(content, regex, "<lastedit>" & FormatDateTime(Date.Now, vbLongDate) & "</lastedit>")
selection.Delete()
selection.Collapse()
Dim ed As EditPoint = selection.TopPoint.CreateEditPoint()
ed.Insert(result)
End Sub
Forms Data Controls :: How To Read Parent Grid Values In Child Grid
Mar 12, 2010I have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
VS 2010 - Restoring Entire Listbox From Session Variable
Dec 31, 2011In my opening page of a web app I create (from a database get) two somewhat large datasets for 2 listboxes. I populate and databind them and all is good with the world
I then want to take those 2 listbox datasets and put them into a session variable for use on other pages of the web app. The reason is I do not want those additional hits in populating the two listboxes again (data does not change)
I am calling a class and passing back a DATASET for each listbox .. then
Session (DATASET_1) = MyClass.Dataset1
Session (DATASET_2) = MyOtherClass.DataSet2
DATASET_1 AND DATASET_2 are defines as constants with a type of DS
When I attempt to rebind the listboxes as
ListBox1.DataSource = Session( DATASET_1 ) *AS System.Data.DataSet ListBox.DataBind()
and the same deal for listbox 2 nothing happens........
Forms Data Controls :: Make Entire Gridview Updatable?
Feb 14, 2011Is it possible to make a gridview so that when it is opened all the records are updatable without having to click on the Edit button? I assume you would have to use the EditItem property and possibly loop through the rows but I'm a newbie and don't know the code.

GridView - How To Programmatically Add And Read New Controls To The Cell
Jun 14, 2010Here is the setup: I programmatically populate my gridview using LINQ to SQL query. Then I enter the edit mode and want to replace some standard TextBox controls with DropDownLists like this:
[Code]....
At this moment I have my gridview showing standard textbox control and new DDList control (in the Column 1).
The problem is -- I cant read the value from DDList in the RowUpdating method. It seems like DDList control is not in the GridView1.Rows.Item(0).Cells(1).Controls collection. RowUpdating method sees only standard TextBox control and can read it's value.
WCF / ASMX :: Read And Modify Soap Message (Programmatically)?
Apr 1, 2011I have a web service running somewhere... I have added a reference of the same in my project. I had used SOAP UI to check the outgoing and incoming SOAP messages.
Now what i need is to MODIFY the SOAP message after it has been created (I wont be creating the soap message manually,) modify as in, I mean to insert some element into the header (such as public key etc) and encrypt the contents present in the body.
I have tried a lot of googling and have come to conclusion that i may have to use the SoapExtension Class.But i just dont understand how to do it.
There are method like ProcessMessage(... which require SoapMessage as input parameter. Now how to read
a generated SoapMessage is still unclear to me. I dont want to read the Soap message using tools (fiddler, soapui etc). I wish to read it programmatically.

Web Forms :: How To Read Checkbox Values From Programmatically Created Checkboxes
Sep 21, 2010I have a form that does a loop to create checkboxes. Here is the code in the loop:
LeftPosition+=120;
cbxDrives.Top = TopPosition;
cbxDrives.Left = LeftPosition;
cbxDrives.Text = d.Name;
CheckBox cbxDrives =
new
CheckBox();this.Controls.Add(cbxDrives);
This creates multiple check boxes on the form, and this works fine.
However, in the code behind for my button that the user clicks to execute the form, I cannot figure how how to read the values for the checkboxes. I've tried:
foreach (CheckBox cbxDrive
in cbxDrives)
{
}
but cbxDrives is not recognized.
I need to read through all of the checkboxes to see their values, so that the appropriate actions can be performed in the code behind.

Make A Menu Selection Programmatically?
Jan 21, 2010I have a page on my website that displays certain ASP charts based off the selection made in a menu control. I'm trying to implement functionality now which will allow me, in certain cases, to make hyperlinks in the columns of the chart control which will result in the current page reloading with specific data. So there are two ways to get certain charts to display: one through the menu, two through another chart's hyperlinked data point.
I would like to handle the hyperlink situation without the use of query strings (if that's possible) becuase functionality already exists for a menu selection plus I'd rather not have to handle user input necessary with any query string. Is there a way to programmatically set the ValuePath property of a menu control which I could (hopefully) do in a Chart_Click event?
.net - How To Programmatically Create An Exchange 2010 Mailbox Using C#
Aug 3, 2010I have been given a task to write a program to automatically create a 2010 exchange mailbox. My research tells me to use powershell but I can't seem to find the namespace to reference and would like some sample code. I found some code on the web but I don't know what the namespace is for PowerShell. I think it might be System.Management.Automation but when I try to reference the namespace it does not exist in the list of dotnet. All I have is System.Management and System.Management.Instrumentation.

VS 2010 - Event Handler For A Button Created Programmatically

Forms Data Controls :: Make A Gridview Editable Programmatically - Per Row
Nov 3, 2010 I have a gridview with bound fields and a templateField that receives data from a submit button which, depending upon the selected object, i.e. dropdown 1, 2, or 3, return a result set. The gridview also has a checkbox column which is used as a marker to determinie the rows to be added to and existing table. If a user selects multiple row, those rows are written to the database. Everything works.
Now, I need to add additional functionality to the gridview:
Upon selecting the checkbox, programmatically the accompanying row must become editable; for each row presented.
Deselected the checkbox, return the gridview row to a read-only state.
There are 14 columns, one of which is a dropdown which needs to maintain its default value.

Conditionally Make A DetailsView Field Read - Only?
Jan 26, 2011Say I have a DetailsView with a bunch of fields, and I want only certain kinds of users to edit a few of them. They're too few to split them into another DetailsView, so what I'm thinking is to find some way to only allow a user to edit them based on some code-behind logic, effectively making them read-only at will.
I feel it's important to mention that the fields are both TemplateFields, not normal BoundFields with ReadOnly properties. For some reason the required functions don't jump at me from reading the documentation. Oh and I need eveyone to see their specific values, I just want to restrict edit access to them.

View 3 RepliesVS 2010 - TextFieldParser Read Fields Call By Name Instead Of Position
Oct 9, 2012Is it possible to use TextFieldParser and call .ReadFields and then use field name instead of field position?
For example, I have 40 columns in my .csv file.
field 0 = ID
field 1 = brand
field 2 = model
field 3 = price
field 4 = color
field 5 = something else.....
How the data would appear in the file:
ID,brand,model,price,color,somethingelse
1,Samsung,Galaxy S,200,black,xx
2,Samsung,Galaxy S II,300,black,xy
3,Samsung,Galaxy S III,500,black,xy
4,Samsung,Galaxy S III,500,white,xy
Right now I am calling the array like so CurrentRecord(4) which returns the color field value.
Can I call it like so, CurrentRecord("color") which would return the same value?
Code:
Dim afile As FileIO.TextFieldParser = New FileIO.TextFieldParser(sFullPath)
Dim CurrentRecord As String() ' this array will hold each line of data
afile.TextFieldType = FileIO.FieldType.Delimited
afile.Delimiters = New String() {","}
afile.HasFieldsEnclosedInQuotes = True
' parse the actual file
Dim iRow As Integer = 1
