I want to be able to change values in a program that i wrote by using another written program...
like if i want to change textbox1 to readonly during runtime... Well, If it is not worth it, it is not fun - you say programmers are boring but i say they are worth it.
I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10
In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

I have a List of structure's in my VB.NET program, and I'm looping over them, and change the values of the objects in the list, as follows
Dim retvals As List(Of SomeStruct) = parser.RetrieveData(new_path)
For i As Integer = 0 To retvals.Count - 1 Step 1
dim temp as SomeStruct = retvals(i)
[Code]...
When I look into my List of structs after this loop, none of the values were overwritten. Why? I thought that I had references in my list, so if I change reference A to a struct, then reference B to the same struct should see the changes?
I am trying to change values in all the objects on my form.

I am developing a report which outputs data in a SQL Table via an ASPX page, using VB. How do I code this so that all rows containing a "1" for one of the columns, shows up as red? Here is what I have so far. This doesn't cause any errors, but it doesn't show up as red either.
I don't know if this is a problem, but the ExceedsLimit and SixInARow variables are INTs in my stored procs, but then I am declaring them as strings in the code below.

View 3 Repliesi am currently making a project which is to make a cinema screen booking system. My main problem is that although i have most of what is working i need to find a formula to give the full result (overall price) in a label. My other problem is the fact that when i interact with my form certain things dont auto refresh when i change certain values e.g i change number of seats but it doesn't auto refresh the price or anything OR i click one discount then another but nothing changes and it keeps the old value.
Okay in my menu i have a CombBox (ComboBoxScreen) for choosing the film and there are 3 films to choose from in the drop menu each with their own price. I also have a Textbox (NumberSeats) for inputting a number of seats you want to book for chosen film. And lastly there are 3 radio buttons each with different discounts. e.g No discount, 10% off and 25% off. A formula to work out the overall price uses all three functions/tools above. [Code]
i have a textbox with hexadecimal values and i would like to use the slidebar/scrollbar to change the values (increase/decrease) then save the final values to a text file. To prevent the program from writing to many times to the file, i decided to use a timer. As long as the user still making changes or controlling the slide/scroll bar the timer will re-load (5 seconds). When the user is done modifying (no more dragging or clicking on the arrows) at that time the timer already expired, then the value get recorded to the text file.

I have created two structures, one named "Product" and the other named "Item". These structures are quite similar but are at the same time quite different from each other. The structure definitions are as follows. Ultimately, I declare arrays in my containing class which access these structures as a type. Their declaration: "Products() as Product" and "Items() as Item". All has been fine and dandy until one day, I go to change the items Enabled() values, and something happens. Not only does it change the Items(index).Enabled(index) value, it does it on the corresponding Products(index).Enabled(index) value, even though it was never specified to do so. Also, nowhere in my coding have i defined this sort of thing to occur. It is rediculous, because I watch it happen. I turn on the watch window, and debug one step at a time, and every time, I watch the Item line step, I look down at the arrays of products and items, and both values have changed. How do I get this to stop, and only change the Item.Enable value??

I want to change the log file filtering at filtering at runtime. I am referring to the traceEventType in the following example.
My.Application.Log.WriteEntry(String.Format("{0:T} DeserilizeProperties", Now), _
TraceEventType.Verbose)
I have found the documentation that allows me to change it in the config file, but I need to do it at runtime. What I am trying to acheive is to allow a beta tester to turn on more detailed logging (according to the TraceEventType...) when encountering an issue in order to email me the log. And then switch back to less detail.TraceEventType.Information)
.Application.Log.WriteEntry(String.Format("{0:T} Send email", Now), TraceEventType.Information)

View 2 RepliesI have made a little bit of code which forces a naturally diverging iteration loop to converge to the value I need, excellent, but it currently is controlled by a button which I click to execute it. What I want to do is to automatically run the module when one of the input parameters changes, to find the new equilibrium value. Forgive me if this is really simple stuff, but I just can't figure out how to do it.

I am currently building a system in SQL Server 2005.
I have a table that holds information about certain insurance schemes such as overheads and other things. These values will change occasionally and currently I administer the database straight through the management Studio.
I would like to build a simple interface that will allow my colleagues to change these values by selecting the company in a dropdown and the current values will populate. They can then edit these values and submit them to the database.
Is this possible in the current Visual Studio supplied with SQL Server 2005 or do I need to get another product.

For a program i have created it shows who the eldest is out of 2 people by them entering their name and age and then the answer is displayed.

how do i write code to stop users entering incorrect data into the text boxes i have provided for their details to enter as well as display a message box.
I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem:
Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad ?
I just need to know how to set up this array within the program to allow 10 values to be entered then later be shown into separate labels as a largest and smallest value.Create an application that lets the user enter 10 values into an array. The application should display the largest and smallest values stored in the array. Figure 8-45 shows an example of the application's form after all 10 values have been entered, with the largest and smallest values displayed.The form basically shows a large label box where your values will show up. Then two regular labels next to the boxed label that determines the largest and smallest values. There are four buttons, a clear, exit, Display Min & Max, and Input Values.I have the actual program layout already made and the initial buttons already declared, being the exit and clear buttons. I just need to know how to setup the array's for the other two buttons.
View 5 RepliesWhat I need to do is to have my program look at 2 different values then return a value.
Here's an example:
If my tube material = SA-214 and the tube gauge = 20 then my tube wall thickness = .032. The thing is I have 5 different types of tube material and 12 different tube gauges so based on which tube material is selected and which tube gauge is selected the tube wall thickness will vary. So if I select a TM of SA214 and a TG of 14 then my tube wall will be .076.
I have designed a program that, when the "caclulate" button (btnCalc) is pressed, it asks the user for a file name, then pulls data from that file (file is a .txt of 100 decimals, one per line) and displays the Total, Average, Highest and Lowest. To do this, I have placed all the data into an array, and then used the array to get the information I need. All the code is in place, the only issue is that when the "calculate" button is pressed and the file name is entered, nothing happens.Need to figure out why the values are not displaying in my 4 labels (lblTotal, lblAverage, lblHighest, lblLowest)!!Here is the code:
