Please give some suggestion.
Sure...good luck since copy protecting an app is a long and involved process that is out of the scope of a forum posting.

We sell a licensing library, but it only handles licensing and no further - copy protection is a long, involved, frustrating and eventually futile ball game (kindof like golf).
Hit up google for copy-protection libraries. Theres a few licensing libraries around that have copy-protection features - but I can't speak for their effectiveness.

VB.NET 2005
I have some toolbar buttons on my "main" form that i would like to access from another form
Somehow, I have not been able to figure it out ...
Inside the Main window I can use
DriveEnable.pushed =true (where DriveEnable is the name of the actual button in the collection) and that works (of course  )
In my module I'm using
Main.Drivenable.pushed =true .. but it does not work (no error either - just nothing happens)
I have set all "possible" properties of the toolbar tool / button(s) to Public - doesnt seem to help me ..
Whats the missing link ?

Assume Main is a form and not another module/class/object
Are you passing an instance of "Main" to your module.
EG calling the function in your module from the main form
dim oModule as new Module
oModule.CallFunction(me)
Public sub CallFunction(oFrm as Form)
oFrm.Drivenabled=true
end Sub

Hi All,
I am using a datagrid in a ASP.NET page.
The data grid is inside a div tag.
<div id="divEditProjectRes" style="OVERFLOW: auto; HEIGHT: 150px">
<asp:datagrid id="dgEditResource" runat="server" Width="100%">
There is edit option in each row of the data grid and the user can edit on a few fields.
The grid has many records and the user has to scroll down.After scrolling to the record and clicking on edit there is a post back ,and the grid is set back to the top and he again has to scroll back to the row in which now fields are editable.
What I want here is that after he clicks on edit the same row must come at the top and the user need not scroll it again.
I have used the following code in dgEditResource_EditCommand to set focus to the editable text box in the particular scroll row ,Although it gets the focus but again we need to scroll down .
Dim descTB As TextBox
descTB = dgEditResource.Items(e.Item.ItemIndex).Cells(2).FindControl("sdate_edit")
'Set the script to focus and select the TextBox
RegisterStartupScript("focus", "<script language=""JavaScript"">
vbTab & "Form2." & descTB.ClientID & ".focus();"
vbCrLf & vbTab & "Form2." & descTB.ClientID & ".select();" & "<" & "/script>")
descTB = dgEditResource.Items(e.Item.ItemIndex).Cells(2).FindControl("percent_Edit")
If we press tab or space bar the record comes up as focus is already in the text box.
But I need that row to scroll up or navigate by itself after edit is clicked.
Thanks in advance.
Regards,
Sakshi

Have a look at the DateTime class, its properties and methods, including ToString().
BTW: the fastest way to learn a new language is by reading a book about it...

You can try following

I need to extract the value of the folowing column and put it in the startTime variable. This particular query only return one row. I am not sure how to do this and am getting the blue line under lpDataSet.tbl_teach_sched.ts_dayColumn.
startTime = lpDataSet.tbl_teach_sched.ts_dayColumn
|
|
|
|
|
Try something like this:
With lpDataSet.tbl_teach_sched("TableName") <br />
Dim dr As DataRow = .Rows(0)<br />
startTime = dr("ColumnName") <br />
End With
Where "TableName" and "ColumnName" are from your DataSet and DataRow properties.
Hope this points you in the right direction.

By using the dock and anchor properties ( mostly Anchor ) to make the form elements resize as you'd like when the form resizes.

Hello.
I'm making an Windows Installer, and am running into some problems with files not being found (and in turn, unsuccessful/incomplete installs). I think this may be due to my installer File System.
My question: What is the "targetDir" option used for in the below string, and what location exactly does "[TARGETDIR]/" point to? Can I extend this (e.g. "[TARGETDIR]/subdir1/")? If so, how?
"/targetDir="[TARGETDIR]/" /documentName="ExcelAddIn.xls" /assemblyName="ExcelAddIn.dll"

I am creating columns in a dataGrid. I know that I can loop through each row using a for each loop, but how do I make sure that the data from each row is in each column. Can someone tell me whether this will work.
The column ts_day stores each day of the week. So, the column will display Monday, then Tuesday, etc.
' This is the line of code that puts each row from the database in the column.<br />
lpDataSet.Tables(0).Columns.Add(New DataColum("lpDataSet.tbl_teach_sched.ts_dayColumn", GetType(String)))
<br />
' populate the data tables<br />
dtTeachSched = lpDataSet.Tables("tbl_teach_sched")<br />
<br />
' create the data columns<br />
lpDataSet.Tables(0).Columns.Add(New DataColumn("Time", GetType(String))<br />
<br />
For Each row In dtTeachSched.Rows<br />
' This is the line of code that puts each row from the database in the column.<br />
lpDataSet.Tables(0).Columns.Add(New DataColum("lpDataSet.tbl_teach_sched.ts_dayColumn", GetType(String)))<br />
lpDataSet.Tables(0).Columns.Add(New DataColumn("Notes", GetType(String)))<br />
lpDataSet.Tables(0).Columns.Add(New DataColumn("Weeks", GetType(String)))<br />
Next

Sorry, but your question is very confusing to me. What are you trying to do? If you want a DataGridView to display from a DataTable, all you have to do is this:
dgvMyDataGridView.DataSource = dtMyDataTable
If you want the DataGridView to display additional columns after that, you could first add them to the DataTable and loop through the DataTable to fill it...is that what you were asking about??
Hope this helps.

I am creating a datagrid view from multiple database tables. This is how the dataGrid would be laid out. This same layout would exist for each day of the week that this teacher has a schedule.
Under the Monday column the names come from the students database table. The number of weeks comes from the student payments table. This shows how many weeks the student paid for this month. The note in the notes column comes from the the student payments table if the student had paid. If there is a cancelation or some other problem with the lesson that week then the note comes from the lesson status table. The blank row is a time that the teacher is available, but the time slot is empty.
The x's are times that the teacher is not available
Time | Monday | weeks | notes
12:00|john doe| --4-- | -pd- |
12:30|mary doe| --5-- | -pd- |
1:00-|buck doe| --4-- | ns+c |
1:30-|----x---|---x---|--x---|
2:00-|--------|-------|------|
I am using a tableAdapter for each database table but am used to using joins with php.
I have multiple questions.
1) would it be better for me to just do my own query with a join so that I don't have to use all these tableAdapters?
2) Or would it better for me to create a View in the database and query the view.
3) My original question was how do I assure that each day such as Monday, Tuesday, etc that the teacher has a schedule shows up as a column. Keep in mind that I can't simply show what is in one database table as you have shown above.
This is the line of code that I am not sure how it works. Will it increment through the database table rows and for each column that should have a day of the week displayed in it dispay that day of the week.
Here is the line of code.
lpDataSet.Tables(0).Columns.Add(New DataColumn("lpDataSet.tbl_teach_sched.ts_dayColumn", GetType(String)))
This is the code that pupulates that column with a row from the database such as Monday or Tuesday.
lpDataSet.tbl_teach_sched.ts_dayColumn
Keep in mind that when you query this database table for this column it would look like this. The following example is for a teacher that works on monday, Tuesday, Wednesday and Friday.
ts_id | ts_day | teach_id
| |
1 | Monday | 100
2 | Tuesday | 100
3 | Wednesday | 100
4 | Friday | 100
|

This is tricky because you are taking a table that flows vertically and changing it to view horizontally....you will probably have to pull the "Day" table separately....then loop through the day table and add a new column to the grid for each day. then you will have to loop through the rows to populate the data in this new column. Does this help?
