View 37 RepliesAfter user entered a value into textbox (for example 4), datargidview must be create automatically(number of datargidview's columns and rows must be textbox value). And, user enter some values that among 0 and 1 into datagridview's cells. So i want to assing these values (values that are written in datgridview cells). For example, if user enter 0.25 in datagridview's cell 1, and 0.34 cell 2, 0.67 cell 3, and etc, in this instance array(1,1)=0.25, array(1,2)=0.34, array(1,3)=0.67 must be assigned. i hope, i could understand :) i illustrate this example below. i want to assign such as indexs that is written into following example table.

I have created a textbox array based on the number of 'Channels' on another form. This number dictates how many textboxes (and other controls) to add to my new form.
I expect the user to type in their 'type' of channel into each textbox.
The thing I am having problems with is once the user types in the information, how do I access the data and store it for a future form?

I have an application that basicly collects a lot of information on a form, with 5 seperate tabs, prior to outputting this to a text file. Currently the forms are not dynamic in that they contain all the possible texboxes and just hide or show them depending upon choices made. The data is gathered by a function that creates an array of texboxes requiring processing, array being created would seem to correspond to a single line that is being output. The array is moved through item by item and the data gathered then output as a line in the text file. This is repeated for the 80 odd lines. Now a couple of questions, is this the best way to do this?

I was hired by a company to do an Industrial Engineering job, but after some time, I realized that my job was also to design a database manager in VB2008 for the train wheel stock. So I am terribly lost.

I am working on simple handover process from one mobile station to other. I got three proposed results service disruption time, network entry time, connection set up time. I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way.
Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008

View 1 RepliesDoes Visual Basic arrays have the possibility to assign values in one line?i.e. No need to have a loop to assign a value for the whole array.for example,
Dim Array1 (1000) As Integer = 478
Dim Array2 (1000, 1000) As Integer = 852
this means that all values of array1 will be 478 and the other is 852.
