Hey Paszt, thanks for your reply! I have taken a look at the DataSet component, but I don't know how to load an Excel-file into it..? I guess my knowledge is far too little to be able to do what I want.. :( Any hints that can push me in the right direction? :)

Anyone on this? I picked up my programming-hobby again and wanted to try to get further with this. But I'm still unable to determine how often a certain date exists in an Excel-sheet. Also, when I found a certain date in a specific row, I have to check if another value exists in that row (like...

I have found the solution thanks to some guy on another forum, he pointed me to Regex and I have figured out the rest for myself: Imports System.Text.RegularExpressions Public Class Form1 Private Sub Dim GevondenDatums As MatchCollection = Regex.Matches("String to search...

I'm stuck on an issue I think is actually pretty simple but I just can't get it sorted. I have a string containing (a lot of) text, and in that text there are dates. Like 2/28/2010 or 11/12/2007 or whatever. There are multiple dates in that text. How do I get the dates from that piece of text...

I'm currently developing a utility for my job with which you can check how often a certain date or name or whatever is in an Excel-sheet. I have searched the Visual Basic Express help, this forum, internet and other Programming forums for the Range.Find and FindNext methods but I just cannot...

I don't think that's the answer to his question. I'm also looking for a way to lookup specific text in an Excel file.

I'm sorry I don't understand your reply, but that's probably because my English isn't good enough..? Can you explain? :o

OK I have solved my own problem: Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Button2.BackgroundImage = CheckList.My.Resources.Resources.cross_big Button3.BackgroundImage =...

I also tried this: Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Dim CrossColor As Image Dim CrossBW As Image CrossColor = CheckList.My.Resources.Resources.cross_big CrossBW =...

I changed the picture in my first post to text (strange though, image is working fine here at my workplace). And I tried the first suggestion of formlesstree4 but then everytime I click the button, the X is re-set to False (right?), so that's not gonna work...? The button-image changes once and...
