I have an array of 50 text strings, is there any way that i can easily link each item in the array to a different text box on the screen? and then to have the text boxes auto update if the array changes?
View 2 RepliesI'm currently having trouble on my project. I am trying to create a HTML editor application, and I want to incorporate the Code, Split View, and Design elements into my application. The problem I am having is that I want to connect or link two text-boxes (one in code view and one in split view) so when the user clicks on split view or code view the text in the text-boxes will be the same.
View 9 RepliesI have a text file with preferences in it. I read the file and find text on a particular line like this:If InStr(sLine, "avidDirectory") Then This is my line in the text file: avidDirectory "S:Avid MediaFiles" "D:Avid MediaFiles" "Z:Avid MediaFiles"..What I need to do is read each string between the quoations marks and place each one in a text box.I have 5 texts boxes to use if there are 5 different directories above (only three in the example above)So I guess I need to capture the text between the quotation marks, create a new string from it, and place that string into a text box [code]
View 1 RepliesI am trying to write a program that will compare two strings in different text boxes. Then it must add 1 to a third text box for every time a letter appears in both text boxes. So for example if textbox1 said ABCDF and textbox 2 said ABTR it should return the number 2 because A and B appear in both.
This is what I have so far
Public Class Form1 Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles string1.TextChanged
End Sub
Private Sub Compare_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Compare.Click
Dim string1 As String
Dim string2 As String
Dim Result As Integer
End Sub
Function stringcompare(ByVal string1 As String, ByVal string2 As String, ByVal string3 As String) As Integer
stringcompare(string1 As string, string2 As string) End Function End Class
I have a problem in that I have five text boxes pertaining to a customer/client, where there is a txtbox for each: Name; Address; City: State; Zipcode. Of course all the txtboxes are "" at initialization. I also have 2 combo boxes and a 2D array for prices which I have finally been able to understand the array logic. I have also been able to do my necessary calculations for.
My problem. The customer information is first to be validated as all being strings and not empty. The combo boxes I was able to get to tie to my 2 dimentional array and get good output and calculations for a finished product. I am just having problems with the error messages. Also I don't want summary totals unless the data is valid. In other words, the user must enter a complete address and make decisions about the two combo boxes, both of which are needed to use the price array. I will change the comboBoxes to represent dress sizes,"S" "M" "L" and "XL" and the other combobox to describe colorRedSatin or colorBlackBroadcloth with a two dollar difference in price between them. 'That would be similar enough to the problem I need to solve.
Basically I do not want any numbers to appear for price of the dress or addons to the dress unless all validation is complete. I do understand how the radio objects work for discounts and check boxes for accumulating accessories. The program should not give any totals untill the user has input all customer information and made decisions about input from combo boxes and selected calculate from menu. Right now it calculates and puts zeros in when choices are not made from the combo boxes by the user. It will include correct amounts for radio buttons and checkboxes if anything is entered. I need error messages for customer inputs and combo box inputs (if not selected from list of option in drop down for choices) (basically if nothing was put in a text box, the text box is empty. Of course the problem is the user must enter something in all 5 textboxes and not get multiple error messages in rapid succession to fix. We can't always count on our users putting in good data.. When I tried a Do While False with ORs I was getting endless looping. I could not get it to work because it will never execute because the control never passes back to the user.
I don't want to list a series of If/Thens becauser the user will see about 7 messages, where he/she only needs to be fed one at the time. I hope someone can give me some direction. I just need guidance on how to validate the text boxes and combo boxes. The code is analyzed with a "Calculate" on the menustrip. I would like for the calculation not to calculate and put outputs into the summery text boxes unless all textboxes are filled and combo boxes are valid for all the customer information and combo box choices for my two combo boxes describing what is needed for the order to calculate. There are also the radiobuttons and checkboxes, DIMs, Const, Variables, but not having problems with that part I have my indexing problems on the combo boxes worked out also, so I am not concerned about those now except for getting the error messages when I should. I hope that I have described my issues fully. I am using visual studio 8 with Windows 7
I'm trying to make a crossword puzzle. I wanna use textboxes as the cells in the puzzle. I'm also using MySQL as the source for the puzzle data. I need a quick way to easily check and edit the content and properties of the textboxes I'm going to use.I thought I could have an array of textboxes and then access each textbox like this..[code]I declared cell() as a global variable under the "module variables" . The code shows no errors but the textbox doesn't show.
View 3 RepliesHow can you put the out put in an array that has no text boxes? [code]Say this is the code, but what you need is for it to show even more of a break down something like this with the select case.[code]and yet the text file that it needs to read from is delimited by a comna and the amount of the vehicles that are there for the out put changes.I was wanting to use an "If/Then" or an "If/ElseIf/Then" statement nestle into the case statements for the output. What I really need is a place to read some good articles on arrays as I am still fairly new and do not understand fully how they work(which I think is causing my problem.)

View 1 RepliesI need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.
Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.
textblock1.Text = MyArray(0)...
textblock2.Text = MyArray(1)...
textblock3.Text = MyArray(2)...
textblock4.Text = MyArray(3)...
Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?
I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.

I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.

I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I want to create a function that will make a treeView out of link buttons. Then I want to tie all the link buttons to one click event. So each time the user does somethingI will append the users name to the current linkbuttons if the user clicks one of the link buttons a click event is raised and I can extract the text of that button.
Here is an example:
Nick
...user does something...now the link string says
Nick > Jeff
...user does something...now the link string says
Nick > Jeff > Charlie
and so on.
Now I want to give the user the ability to click one of these link buttons (there are 3 in this example). If the user clicks one of the buttons a click event is raised and I can extract the name out of the text of teh link button.

I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.
