Duplication Of Tabpage Layout?
Jul 21, 2010
I've gone through various thread, posts, classes and walkthroughs on sites but seem to be coming up short either in my understanding or what is/should be going on.I have a very simple data entry tabcontrol (think like microsoft excel but textboxes, labels and the odd combobox rather than a grid). When I click one tab it creates a new tab and names it according the sequence (no problems so far). Here is the crotch kicker (for me at least). I need the first tabpage layout on all additional tabpage so that data can be entered in each separately and stored with constant "processing" (adding and subtracting ).What would be the best approach to doing such a tabpage duplication?
Currently a User control library inheriting from tabpage seems like a good idea but with the 40 or so controls on it is this actually going to function like the first tabpage (as in the one i have now not the one I'd have if i used the user control instead).Do I take the raft of code the designer creates automatically for the tabpage and its controls and simply add them to the click event? Would this create duplication problems with name or would it be ok as they would be tabpage1.lblName and tabpage2.lblName?

I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

I am working on an application, where I have already normalized the databases. Now I am creating an application in asp.net with vb.net as my code behind fine. These random numbers would be stored in the Id column. So, no way there would be repeating the keys. But my application could generate the key, which would probably get repeated. How would I check the database for, so that random numbers wont get repeated? is there any function? Could you give me the code for the same.

This is a simplified version of a class that I have in my project. Since the Bonus is figured the exact same way in each function I want to remove the obvious code duplication that appears here and make the three different functions into one. However I am not sure how to provide the argument that this new function would require.
For instance I am currently just passing the argument like this from code
lblVolumeBonus.Content = TestClass.VolumeBonusAmountStore(bonus).
I think I have to basically turn this logic around and call it with something like
lblVolumeBonus.Content = TestClass.VolumeBonusAmountStore(BonusTrackerBO.StoreBonus)
but I am not sure of the correct syntax or whether I am on the right track at all.
Public Class TestClass
Public Shared Function StoreBonus(ByVal bonus As BonusTrackerBO.StoreBonus) As Double
[Code]....
Edit: It may not make a difference but I should have made clear that there are other factors in the equation (I was just trying to keep it simple). So is the answer the same when there are other callbacks to the bonus like bonus.MaximumAmount, bonus.MinimumAmount? There are 5 callbacks to the bonus object and the amounts are different depending on whether it is a Store, District or Company asking.

Am developing a resume data retrieving software where data is stored in one parent table and 4 child tables as such:
Resume_table ----> Parent table
holds ----> Res_ID, Emp_ID, Lang_ID, Task_ID & some other static data
Employee_Table--->which is referenced directly to Resume_Table.Emp_ID similarly ol other 3 tables are referenced to the main parent table Storing and retrieving data is all working fine as long as I am retrieving 1 record for each child tables But some times there might be couple of languages and only single records for other child tables.In dat case as the four child tables are ol in separate subreports whch are called onto the main report whch prints as cv gives redundancy in data i.e by giving duplication of ol records twice which were single records during entry, which i think follows the language table if it consist of 2 records.am using a join query to call these records onto crystal report...

I'm trying to create a 'lottery machine', I've included the code i've been using below. I've got 7text boxes, ad numbers are between 1-49. I need to stop the duplication and to sort them in ascending order (1-49), i've tired a bubble sort but that hasn't worked, and a 'if, while' process, but i think it might be wrong! I know its a little pushy but i could do with this being sorted before 3pm friday 29 january 2009! I would be so greatful if anyone can even point me in the right direction as i am new to visual basic.

Reading through "The Pragmatic Programmer", I've come across the DRY (Don't Repeat Yourself) and Orthagonal (keep code modular) principles.I have a suite of modules, some of which have common procedures. Because each module is a separate project in Visual Studio, up until now I have simply copied code from one project to another when 1 module (project) needs to do the same function as another module (project). This is when functionality overlaps, not when 2 modules (projects) do everything the same.
I always suspected this was bad practice (and have seen the fruits of my suspicions when the subs get out of sync), and the book confirmed me in this belief. So, what I want to do is make a central code repository for the 4 or 5 common subs, but I don't know how to do it.Should I make a .dll file for each sub I want to use in multiple places? If so, how do I do that? Is there another way to do what I want to do?
1. I have a subroutine that takes a filepath (and if disconnected also a SqlConnection) and loads the referenced file into a database as a BLOB.
2. I have 3 separate projects in 1 VS solution that all run basically the same version of this code.
3. I want all 3 to run EXACTLY the same code.
4. I want 1 version of this code so that any changes made don't need to be made in 3 places.
5. I have a few other instances like this for other subroutines.

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
