Find Last Created File Begining With A Number?
Nov 3, 2010
I am runing a third party application which creates a file in c: with the file name as "982345612_". Please note that the numbers are generated randomly and can be anything between 0 and 9.
What i want is that as soon as the file is created i want to read the first nine number from the file name and show in a label in my form. I have no control over file creation but through my form i want to read filename as soon as the file is created.[code]...

I support applications in VB6 and VB2003, and I'm trying to upgrade the VB6 app to VB2005, so I have three versions of Visual Studio on my pc. I ran VS2005 and opened the VB6 app to launch the upgrade wizard. It seemed to run fine until it threw an error saying it could not find the project it just created. The project I'm trying to upgrade is called MGxFromSAP.vbp. The error said it could not find MGxFromSAP.vbproj. The project file it actually created is called MGxFromSAP.vbproj.vs7.vbproj. When I try to open this project in VS2005 it says it was created in an earlier version of Visual Studio and needs to be upgraded.Did it perhaps invoke the VB2003 upgrade wizard instead of the new one? How would I be able to tell?
Should I just let VS2005 upgrade the vs7 project or should I try to deinstall the old VS2003 upgrade wizard and rerun the upgrade from scratch?

Am using VB 2005 and need to take an existing txt file which basically has 15 sets of data, each set containing a year (ie Year 1990) and a number below the year.
When a user clicks the calculate button on a form, I need it to first list the average of all those numbers in the txt. And below that I need the largest number in the file to be displayed.
I am basically familiar with using objReader and StreamReader. But, I can only verify and open the text.

I'm new here, but have been in and out for a while. Past threads have been helping me along thus far.
I'm currently developing an app which essentially needs a way for me to search in a text box or file for a specific string, and extract the line on which that string appears on. It will be unique, and the syntax is the same on each line. It has basically 2 ID numbers, and is laid out like this:
123456|123456
So, I'd need to search for the first part before the |, and then get the line so I can get the bit after the |, which is the important bit for me.

I have some variable that when divided I get this symbol: -1.#IND when you look at the variable in debug. This only happens when I put the equation in the Dim statement.
[Code]...
I don't have a problem. Why when I put the equation up in the declaration area it sets it to -1.#IND (I assume this is infinite or NAN or some such). I'm curious as this is the only time I've had difficulty with this.

I'm very new to programming with Visual Studio(just a few weeks). I've read through a beginner's book and I've started to write my first little programs to get used to coding and to improve my skills. One of the first programs I had created was a simple currency converter. I've created a list box and a combo box with a number of different currencies in them and I want to know if there is an easy way to attach a value to each of these selections. For example, if someone selects British Pound in the list box and Indian Rupee in the combo box, I want to be able to have the British Pound be worth 1.67(versus the dollar) and the Rupee to be 25.00(versus the dollar) for example so that I can create a simple function that will change pounds to dollars and then to Rupees so that I can do this calculation with a multitude of currencies. If you have some idea of how I can attack this problem,

I am creating an application and I have the numbers 1 - 20. Each number represents a location. They are continuous. I need a way to find the closest number to a given location. For example if the event is in location 8 and there are 2 people who can attend who are in locations 6 and 10. Then zone 6 would be chosen as its closest and also the lowest. If I needed the next highest closest number then I could pull all of the numbers into an array and sort them and then pull out the one which is the next highest zone. However as I need to find the closest number which could be lower, im not sure how to achieve this.
