Thanks for your time.
Actually I tried to read the print job status using a API:
A seperate program will polling and writing the status to aceess and after the print read command read the access to check if that document reached the status printing. here for very small documents i may not be able to read the status and that time i used to wait for 30 seconds.
This works fine but the pproblem now is that some of the PDF documents printed with only one page. The remaining pages are missing. I am giving the next print command only after the previous document status in printer is "printing".
The same behaviour when i print without any delay . But no missing of pages when i print with 15 second dely.
Any idea why this is happening.
Thanks and Regards

I've never heard of the problem. Sounds like an issue with Acrobat, or whatever component is doing the printing.

hi friends,
i have a datagrid in my project and i m using a datatable to fill the datagrid.the default preferredcolumnwidht property is set to 200.
but i want to use datagridtable style and disply the columns with different widhts but all efforts til now went in vain......
the code i used is pasted below..........
plz help me.
the code for style whihc i used is commented.....
hoping for quick solutions.....
Dim lDataTable As New DataTable("ItemList")
mintRecCount = Datasource.Length
lDataTable.Columns.Add("Code", System.Type.GetType("System.String"))
lDataTable.Columns.Add("Description", System.Type.GetType("System.String"))
lDataTable.Columns.Add("UOM", System.Type.GetType("System.String"))
lDataTable.Columns.Add("Quantity", System.Type.GetType("System.Int32"))
'lDataTable.Columns.Add("AltQty", System.Type.GetType("System.Int32"))
lDataTable.Columns.Add("Weight", System.Type.GetType("System.Single"))
lDataTable.Columns.Add("Price", System.Type.GetType("System.Single"))
For mRowIndex = 0 To mintRecCount - 1
lDataRow = lDataTable.NewRow()
'code for entering data into the datarow
lDataTable.Rows.Add(lDataRow)
Next mRowIndex
lDataTable.Columns(0).ReadOnly = True
lDataTable.Columns(1).ReadOnly = True
lDataTable.Columns(2).ReadOnly = True
lDataTable.Columns(4).ReadOnly = True
'Dim ts As New DataGridTableStyle
'ts.MappingName = "ItemList"
'Dim cs As DataGridTextBoxColumn
'cs = New DataGridTextBoxColumn
'cs.MappingName = "Code"
'cs.HeaderText = "Code"
'cs.Width = 64
'ts.GridColumnStyles.Add(cs)
'similiar code for other columns
'dgOrdInvAddItem.TableStyles.Add(ts)
dgOrdInvAddItem.DataSource = lDataTable

Here is some code I used in one of my projects and it worked quite fine. Hope it helps...
Private Sub setDGProperties()
dgDetails.TableStyles.Clear()
Dim dgts As New DataGridTableStyle
dgts.MappingName = "TransDetails"
dgts.AlternatingBackColor = Color.LightGray
Dim prod As New DataGridTextBoxColumn
prod.MappingName = "ProductID"
prod.HeaderText = "ProductID"
dgts.GridColumnStyles.Add(prod)
Dim cname As New DataGridTextBoxColumn
cname.MappingName = "ProductName"
cname.HeaderText = "Product Name"
cname.Width = 120
dgts.GridColumnStyles.Add(cname)
Dim quan As New DataGridTextBoxColumn
quan.MappingName = "Quantity"
quan.HeaderText = "Quantity"
dgts.GridColumnStyles.Add(quan)
Dim price As New DataGridTextBoxColumn
price.MappingName = "TPrice"
price.HeaderText = "Price"
price.Format = "C"
dgts.GridColumnStyles.Add(price)
dgDetails.TableStyles.Add(dgts)
End Sub

Ok guys,
This might be a simple question (I hope it has a simple answer). I have a program that gets a handle to an event by using GetEnvironmentVariable. My question is... How do I set this event?
Any sample code would be great!
Thanks,
Waffleman

WHAT??? Would you like to post some code?
An environment variable doesn't have anything to do with an event handle...
Are you saying that you want to fire an event if your app is asked to return an environment variable?

Let me clarify, I looked a little more and I am not getting the handle. Instead I am getting the object name. In a similar C++ program the code looks as follows:
if( GetEnvironmentVariable("Notify",szValue,sizeof(szValue)) )
{
hEvent = OpenEvent(EVENT_ALL_ACCESS,FALSE,szValue);
if( NULL == hEvent )
{
printf("AppStarted OpenEvent failed %d <%s>\n",
GetLastError(),szValue);
goto RET;
}
}
if (!SetEvent(hEvent))
{
printf("AppStarted SetEvent failed %d <%s>\n",
GetLastError(),
szValue);
goto RET;
}
}
Here is a link to the details of OpenEvent in MSDN:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/openevent.asp
So how would I open this event and set it in VB.NET?
I hope that makes more sense...

Yes it does... Your C++ code, which I assume your trying to duplicate in VB.NET, just gets the name of an event signal object. Now, it uses that name to open the event object, provided that it already exists, then it sets the object to signaled. This is used to nofity other threads in an application that an event has happened.
What does you VB.NET code look like? With the OpenEvent function, all you get back IS the event handle, if it exists. The Environment variable is just there to supply the name of the event your getting the handle to. This event object must be created with CreateEvent in some other process before your VB.NET app can Open it...

Here is the only VB.NET code I have:
Dim szNotify as String
szNotify = Environment.GetEnvironmentVariable("Notify")
DebugPrint("Notify: " & Notify, 1)
If (szNotify.Length > 0) Then
'** Set Event
End If
The event signal object is created by the parent program that kicks off the program that I am currently writing in VB.NET. The object name is stored in an environment variable. Right now I am just unclear on how to, when given an event object name, open the event and raise it in VB.NET.

It's stored in a cookie and encrypted. You're not retrieving the password from a cookie without some serious decryption code, that we're not giving you for obvious reasons...

Yes, the password is stored on your computer. There are a lot of utilities to decrypt them. Try this website[^]

To add in a program an istruction that, in the moment in which it runs. ..."pause" the program?
...imagine to have a program that it is doing varied things...exists a wayto say..."Stop" (for example) for 10 seconds without makeing nothing and then "restart at the stop point"? (Everything without to have "closed" the program.....but only as likeas it was "in wait?")
Thanks early to all.

?????  It's very difficult to understand you, but I'll take a crack at this...
I take it you want to put your code to sleep for, say 10 seconds. Simple... Use Thread.Sleep(milliseconds As Integer), or Thread.Sleep(TimeSpan):
Imports System
Imports System.Threading
Thread.Sleep(10000) ' Puts the current thread to sleep for 10 seconds.

Start your Computer Management Console (Start -> All Programs -> Administrative Tools -> Computer Management)
Navigate to Users in the Console ( System Tools -> Local Users and Groups -> Users) and select your user name. Right-click on it, select properties, then select the "member of" tab, and Add the Debugger Users group.

You will need to be an administratror to change these settings. If you're using your college pc, you might need to ask the administrator of the machine to add the group for you.

Hi,
After I got DateTime from Calendar (ie: fDate = July 04,2004), the date is showed by Debug program is 07/04/2004 but after I using:
strSQL = "SELECT * FROM Invoice WHERE InvoiceDT >= " & fDate>
---> some how it converted fDate back as 04/07/2004 (April 07, 2004) and when execute the SQL I got wrong result!
*) If I get the date later than 12 then there are no problem because MS detects it (ie: 30/06/2004 or 06/30/2004)
1. How can I correct this problem?
2. Do I need special syntax in string SQL for DateTime? (I did try add "#" & fDate "#", the result is the same!)
Many thanks for any help,
Anh

ALWAYS, ALWAYS, ALWAYS, ... continue for 10 more minutes ..., ALWAYS use PARAMETERIZED queries!
Using a parameterized query will automatically make sure that the date is translated into the appropriate format for the SQL statement. Also, the reverse is true. Any date that is returned will be converted back to the appropriate format for your code.
This is an example from a project I am working on:
Try
oConnection = GetDatabaseConnection()
oCommand = New SqlCommand
oCommand.Connection = oConnection
oCommand.CommandText = "SecurityValidateLogin"
oCommand.CommandType = CommandType.StoredProcedure
Dim sqlParam As New SqlParameter("@Username", SqlDbType.NVarChar, 50)
sqlParam.Value = sUserName
oCommand.Parameters.Add(sqlParam)
sqlParam = New SqlParameter("@Password", SqlDbType.NVarChar, 15)
sqlParam.Value = sPassword
oCommand.Parameters.Add(sqlParam)
sqlParam = New SqlParameter("@SourceIP", SqlDbType.NVarChar, 32)
sqlParam.Value = sSourceIP
oCommand.Parameters.Add(sqlParam)
oConnection.Open()
oCommand.ExecuteNonQuery()
oConnection.Close()
' code removed
Catch ex As Exception
LogErrorEvent("SecurityServices", "ValidateUserLogin", ex.Message, ex.StackTrace)
Throw ex
Finally
' Trash our open objects
If Not oCommand Is Nothing Then
oCommand.Dispose()
End If
If Not oConnection Is Nothing Then
If Not oConnection.State = ConnectionState.Closed Then
oConnection.Close()
End If
oConnection.Dispose()
End If
End Try
Return retValidateValue

Hey Dave,
Under what circumstances should we be using parameterized queries? 
Charlie
if(!curlies){ return; }
|
|
|
|

all, alL, aLL, ALL OF THEM I SAY! MUAHAHAHHAHAH!! 
But seriously, for those who read the posts long after we put them up (yeah, right )...
If you have an SQL stored proecdure or statement with a WHERE clause in it, always use parameterized queries to call it! It will save you a bunch of headaches like the original poster had. It's not hard to do, maybe a little tedious, and it's very easy to follow compared to some of the monsterous string built queries I've seen.
