I have developed a vb.net application, which searches for different kinds of dates from a document. When i test the app on my Windows 7, VS2010 PC, the dd/mm/YYYY date read as string is correctly converted to valid date format, and then it can perform followingfunctiontstimespan =Date.Now.Subtract(Convert.ToDateTime(DesiredMatch.Value)).DurationIt works fine on development PC. But when i test the application on my client PC having Windows XP, it throws an error 'string was not detrmined as valid date time windows'.

When I run my program, I want my AverageInventoryTextBox to be formatted like $0.00 and my TurnOverTextBox to be 0.00 (2 decimal places)But when I do the strings for the textboxes and run the program, no matter what numbers I put in it just gives me $0.00 and 0.00, it SHOULD be like $13.84 or 7.44 something like that, but it will only give me zero for an answer.

I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.

I am trying to bind a textbox to a binding source (using the IDE DataBindings Editor) and it works fine except for one thing: if I delete the text I get the subject error. What I want to happen is the datarecord field be updated to a dbnull value -- how do I get that to happen?

I want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?

Has that function been deprecated? If so, what is the alternative?

I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

I'm currently working on "transferring" my vb6 application to vb.net. I'm doing a complete rebuild from the ground up - which allows me to address issues that have arisen over the life of my vb6 application and I'm also learning .net as I work. My primary concern though, is that on one of my forms I display all the information about a customer (Name, Address, Notes, Phone Number, Assigned Salesman, etc.) in VB6, I put all the textboxes in a frame and disabled the frame so they boxes looked "normal", meaning there were still white with black text. In .net, if I add the textboxes to a

My application has to do a lot of work when I press as single button. When he is doing this he got to changes sometimes a few tings in a textbox. Sometimes the calculation can take more then 10 - 15 minutes, is there any way to make it doesn't say not responding? And you are able to work further in the program. I did try backgroundworker but I'm not able to edit the textbox.

I am using the following code to filter on a textbox value using the BindingSource.Filter function.I thought this was the right code based on my many searches.
BindingSource1.Filter = "ValueID = '%" & ValueToFilter.Text & "%'"
When do a debug, it shows the correct value which is "432360ac-ac35-4101-8d46-f2cbd5b5dc52.There are spaces in the end of this value and it is exactly the same in the SQL database with the spaces. ValueID is a column in my SQL server. It does not filter the records in my dataset.I tried replacing the ValueToFilter.Text with my actual value as shown above including the space at the end and it filters the records just fine exactly as I want it to. Although I obviously need it to work for multiple values from my SQL server.
