I currently have 3 combo-boxes called 'cboProduct, cboProduct2 andcboproduct3' and next to each one of them I have a textbox called 'txtQty1,txtQty2 and txtQty3'. I am trying to get the first combo-box to find the first free row starting from A21 and go to cell B21 and the first textbox to go to D21. For the second combo-box to find a free row from A21 and go to B22 if B21 is used and the same applies to the textbox , if D21 is used to go D22.This also applies for the third combo-box and text box. However my coding doesn't work.

View 2 RepliesQuestion is related to rather simple programs typically presenting some data in a few datagridviews, charts etc. And consisting typically of a main form and one or two settings forms.I'm trying to program in a layered structure, pulling every bit of code out of any form class, and having a seperate "program class" for any form that I make. Now.. So far you can't complain on that I guess, but how to do this in best coding practice? In the form class I make a member object of the program class, hence making the program class a child of the form. Now I'm able to create events in the child class, and have handler methods in the form, without writing delegate classes (it seems). Now, that is fine, as it enables me to update the form controls with such events happening in the program class. However, how do I send events the other direction, from the form (parent) to the program class (child)? I guess I don't have to use events, I could just use the member object to access public methods in the program class directly, with passing of parameters from the form controls.. however, is that good practice? Or should I use events also that direction, and how to make that work, do I need to introduce delegate classes

View 5 RepliesMy form contains lots and lots regular expression and other things in one button. whch when pressed takes some time to process.. so the form kind of gets stucked while the processing is bieng done.is there any coding for which it diables the entire form until the process is completed? like disabling the entire form and showing a text "please wait ... processing data" so user can not use other buttons or features at the same time or it might get crashed.
View 5 RepliesSay we have a DataGridView on the main form. I can chose to establish its properties by code or by selecting them in the Properties panel. Is there a difference between these two techniques, a loading time penalty in any of the cases especially?
View 5 RepliesI have created a (kind of) 'Desktop' Form for the main basis of my program. Basically it is made up of 3 panel controls.
1. Holds all buttons which load the different forms (Like the windows start menu when expanded). name: StartMenuPanel
2. Holds Information on log in deatails. name: LogCheckPanel (very thin panel at top of screen)
3. Main panel which takes up the majority of the screen (where I want the forms to load). name: MainPanel
My aim is: When a button is clicked from the 'StartMenuPanel' the form will load with-in the 'MainPanel'.
I tried changing the start position to 'centre parent', but the panels are in the way so some of the childform is overlayed by the panels.

When I run this I get the following error: 'Top-level control cannot be added to a control'.
I hope I've explained this well enough.
I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

I have a solution with several projects most of which are code or control libraries. I have a main windows forms application that references and uses these libraries. What i am trying to do is create a 2nd windows application that extends the main one, but i would like to be able to deploy them as separate exe's.
When i try to add a reference to the new app referencing the main app; all seems fine until i try to run the new app i get several error msgs similar to below:
Error 1 Could not find file 'ADODB.dll' referenced by assembly 'D:Visual Studio 2005ProjectsXXXinDebugXXX.exe.manifest'. <newAppName>
i have tried adding references to all the dll's in the error messages and they are still listed when i try to run the new app. I thought of a few work arounds but they require user changes to maintain separate exe's at deployment. I would like to avoid this if possible.
