I was wondering what the easiest way is to get a portion of text from a string for example, you have:
"example1,example2,example3"
And i need to be able to get all three of the items separate:
"example1"
"example2"
"example3"
The length and number of items will change, I'm using a listview subitem
I am working on a small program that reads items from a text file. The items are the split up into data and used to fill the menuItem() as menuItems. Each instance of menuItem has 3 properties (name(string), price(double), and menuType(string)). As an item is selected, it's price is added to the Order collection with :
Order.Add(menuItem(index).price)
The running total of the sum of the selected items is to be displayed in text box. I have,
txtTotal.Text = FormatCurrency(runningTotal()) ' with runningTotal as a function
Function runningTotal()
For Each menuItem As MenuItems In Order

However, when run, this error appears. This is new coding to me, so if I'm just way off, let me know. Anywho, I tried with & without the CDbl. It doesn't seem to have any effect.
I have a MyDataGridView.DataSource = MyDataSet.Table(0) and the AllowUserToAddRows = True Once the user have finished typing in the column zero I have to check if they didn't type invalid stuff. It have to be numeric and 4 chars long.
the code is:
Private Sub Result_CellEndEdit(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles Result.CellEndEdit
If e.ColumnIndex = 0 Then

And it is not all the time, but depending on how quick and stupid (i'm expecting stupid users, as usual) I click on the previous row or the AddNewRow row I get a the damn System.NullReferenceException on my If line:
If Not (IsNumeric(Result.Rows(e.RowIndex).Cells(0).Value) And Result.Rows(e.RowIndex).Cells(0).Value.ToString.Length = 4) Then I'm really not in the mood of just put a Try Catch, as it looks like bad programming in this case. I've already tried a couple variations with "is nothing" but no success?How could test it won't cause a Null exception before testing the row value?
So i make a program that saves text files in one folder, but what i need is to make the file limit in folder..For example, i have limit 200 files, and when i add a new file, how do i delete the oldest one, or if the limit is changed to 100, how do i delete all the old ones, to make the limit 100?
View 2 RepliesI'm using My.Settings to store some text information which will be displayed to the user under certain conditions. What I'd like to know is whether part of the text (not all of it) can be formatted in bold?
The reason I'm storing in My.Settings is because it can be customized but not to the extent where I need to store it in a database. And while I'm at it, is it possible to format parts of MessageBox text and labels in bold, or is this an all or not at all situation i.e. changing the font property?
I'm currently in a situation where I need to uninstall a certain program from a local computer (and automatically install a newer version of that program), because this old version of the program randomly causes my program to malfunction I have found this article:CodeProject: How to list all Programs installed on Computer and Uninstall Them . Free source code and programming help This shows how to start the uninstall program for the programs I need to uninstall, which is a good start. I also have created all the code needed to install the newer version of the program But as this program will be used by users, I want to minimize the number of times the users has to do something. So far the only popup that I haven't been able to get rid of is when the uninstall program is being run how to force it to uninstall without having the program ask for confirmation?

View 2 RepliesI have a program with which I can open a second form on a beamer, this works perfect, but what I do notice it that on the taskbar (I have windows 7) I see the main icon of the app but also the form that is created.What I would like is that the second icon is not displayed on the taskbar thumbnails, this way I can't close the second form by the X but only by a button on the main app.
View 2 RepliesI spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.
I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

I'm also pulling info from the bios, disk drives, video, etc. What I've noticed, is although it runs fine on my pc, it may error out on some pcs since it is hardware dependent.I'm having trouble implementing a check to find if it exists before I convert to a string and add it to my overall string.
I'm working on a mass text replacer program because I'm sick of all the 10-day trial ones out there that aren't very good.The entire program is basically finished (All easy stuff), but now I need to code the actual replace/delete stuff, which I'm stuck on because apparently the way I originally intended to do it is not possible.
The way it works is you load a text file (.txt, .cfg, .ini, .doc, etc.) which opens a StreamReader which writes all the data into a listbox. Then you pick whether you want to replace or delete a string. If you select replace, then you enter the string to search for and in another textbox you enter the string to replace it with.
The way I originally intended to do this was like this:
If o1.Text = "Replace" Then 'The option
Replace(txtfile, str1, a1) 'txtfile is the data, str1 is the string to find and a1 is the replacement
End If
The problem is, I believe this method requires txtfile, str1 and a1 to be strings, but they're all 1-dimensional string arrays, which cannot be converted to strings, or at least I don't know how to convert them.
A friend told me one way I could do this is to open both a StreamReader and StreamWriter and do the replace/delete line by line as they are entered into the memory and write them to a temporary file which is then copied over the original. I can do this kind of, but I still don't know the proper way of doing the actual replace code because the string to find and the string to replace with are still 1-dimensional string arrays rather than strings.
