Select p).Single
tout.TimeOut = DateTime.Now.ToString("HH:mm:ss")
datacontext.SubmitChanges()
Is there a simple way that I can replace a foreign key in a datatable, with a corresponding value from the table that the key is referring to, without having to create a new table or use tableadapter? Ive got a table that has a foreign key to a child table, and I need to get a column from that table to fill a dataview?
i have a problem in locating bookmarks which are defined inside the table cell. Each table cell in my word document can contain multiple textboxes. I need to fill text in each of these textboxes using word automation. I tried placing bookmarks inside these textboxes for each cell and tried to replace using Word Automation. But unfortunately, i cant locate / replace the bookmark using the following lines:
cell.Range.Bookmarks.get_Item(ref oBookmark).Select(); //this is throwing exception as it couldnt find bookmark in cell.Range.Bookmarks list.cell.Application.Selection.InsertAfter("New Text");

This is my first time working with VB, though I've been working with VBA for a couple years now to automate office routines at my work. At my last job, I saved about 3 hours a day with my automations, and at my current job, I'm shooting for about the same. The problem is, though I have a high affinity for computers and technology, I never studied to be a programmer, and so I really can only tweak code I find online, and then eventually build up enough of my own subroutines to accomplish the tasks at hand. This is why I'm posting here on this forum, I've reached my wits end for what I imagine is a relatively simple problem. This was initially written in VB 6, but I imported and converted it with Visual Studio 2008, and it runs fine. This demo code is set to populate a PDFwith some sample string text. What I want to do is to replace the string text with a reference to data in either an Access or SQL database - I prefer Access, but either will work. Here is a sample of the demo code I'm working with:
[code]...
On this last line, I want to replace the "1" sting text with a reference to a temporary 1-row table I'll be generating from an Access Query, with Field Names to match the Form Field names of the PDF, So I've setup an Access DB with the following configuration (in reference to the path, I'm using Vista x64):
[code]...
I have also imported this table as a dataset (my understanding is that the import into Visual Studio 2008 makes it a typed dataset?) so either referencing the access DB directly or the imported Dataset should work. I can also setup the Access DB as a SQL DB instead if it would make it easier. Now, if I was programming in VBA, I might do something like this:
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
I M using small application it has two textbox i m put data in textbox1 and find output in textbox2 i want to do mulipal replace text in textbox2 like
Quote"KB" to "kilobyte" "MB" to "megabyte" "GB" to "gigabyte" "TB" to "terabyte"
For this i m using this Code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click TextBox2.Text = TextBox1.Text Dim i As Integer = 0
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public Sub Main() Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate As String
I'm working on a timekeeping application in Visual Basic 2008 and am having trouble formatting a timespan for display. Here's how I want to the information:If a positive number my Label will be: lblTimespan.txt will show as "12 Hours And 15 Minutes" This works fine.If its a negative number I want to display it as "(12 Hours And 15 Minutes)'[ in red. The problem is that I can't get rid of the minus sign. [code] Thr Replace doesn't seem to want to replace the "-", can anyone suggest what to do?
I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString") Private _myObjectLongName As New ThisObjectLongName("SomeString")
