In order to organize various methods of my MainForm class, I would like to categorize them into several files. Of course, the methods would still need to access form elements and additional variables I added in the MainForm class.
View 3 RepliesThis has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:

I'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea. There are certain methods and properties these controls all need to work within the app. Right now I am doing this as an Interface, but this is aggravating as all get up, because some of the methods are optional, and yet I MUST implement them by the nature of interfaces.

Since you are repeating same operation three times it is best to make a function for it.
CODE:
labels 1-6 are randomly generated numbers, text boxes 1-3 are the input boxes and the code above shows how if the answer in the textbox equals the labels added together, you win. This code works -
I have created labels 7-12 now, and textboxes 4-6. How can I extend this program so it has subtraction as well?
If this problem definition isn't detailed enough, let me know and I'll add more detail to this description.
is there anyway to extend upon an existing Interface? i'm just wondering.

View 4 RepliesI reference several 3rd party libraries in my application. I want to put all of these libraries in a folder that is different than where the executable file for my application is located. I would also like to put all of the libraries that are required by the 3rd party libraries (but not referenced by my application) in this same folder.
I need to be able to put the application (and the referenced libraries) on a thumb drive and run the application from any computer without any installation or registering of components. This condition is satisfied if I put all of the required libraries in the same folder as the executable.
For example, if my application is located at E:MyApp then I would like to store all of the 3rd party libraries in the folder E:MyAppDlls. Any way to store all (or at least some) of the libraries in a separate folder?

View 3 RepliesI need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.
Is it possible to extend the MyApplication object - either through inheritance or by using a partial class - so as to add custom properties?

Has anyone ever used Game Maker 7?
I was wondering, if anyone had any information on making DLL's for this software to extend its function list.
Correct the problems with this function, and then extend it so that it also returns a usable array of pointers to some structures.
The extended version of this function should: Maintain the same "char *" return type which returns a pointer to a usable, for storing a C string, memory buffer.
In addition, also return a usable array of pointers to structures. This array of pointers is of variable and random length, which must be obtained using GetNumberOfSomeSeqsToGenerate(), which is called, ONLY, from within this new extended version of the function.
The type of these structures and the function that should be used to get these structures are defined as follows:
typedef struct {
char* name; /* '\0'-terminated C string */
int number;
} SomeSeq;

I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
