View 5 RepliesInterface And Graphics :: Popup Selection From Dynamic List?
Aug 8, 2008Is the ContextMenu control strictly to offer choices when the user right-clicks some object, or can it be used to offer choices in general?
In my situation, when a user opens a certain type of file, I want to offer a selection of specific subfiles (line ranges) within said file as choices. The presence of subfiles and their number is variable, so this would be a dynamic situation. (No subfiles: use the whole file; three subfiles: present three choices ...)Would ContextMenu be appropriate, or should I offer a list box or combo box or frame of radio buttons instead?

Interface And Graphics :: TextBox Not Updating?
Nov 23, 2010I'm trying to update a text field... in this manner:The main form (where I have the design):
Code:
Public Class Form1
Public Sub ChangeTextBox(ByVal vVal As String)
TextBox1.Text = TextBox1.Text & vVal
[code].....
First I click on the button to open the port. Then I do this code so whenever I receive data from a serial port connection, "Hello" string is written in the text field.. I debugged it, made sure COM Port is open, and data seems to pass to the textbox.. because when I put my mouse over to display the values inside the textbox it shows that "Hello" is stored.. and I tried doing the textbox1.refresh() but still nothing happens.. the textbox remains empty!
Interface And Graphics :: Line Breaks In TextBox?

View 4 RepliesInterface And Graphics :: Redrawing A Textbox On A Context Menu
Oct 17, 2008I'm working with adding some user-friendly options to a program that I've developed. A lot of these require handling painting the control myself. So far this hasn't been an issue except for this case.In a context menu, I have a text box that a user can type into. However, the context menu doesn't seem to let me input a label next to it so that the user knows what the text box is for. So, I wanted to paint the text box myself but I can't get the routine to work.I have tried to put the following code in the paint event for both the context menu and the text box itself. In the paint method for the context menu, the string and the text box show up at the top of the menu. Not 3 items down like it should. Also, I don't think the end result is truly a text box.[code]I believe that txtRect is set to the rectangle for the context menu and not for the text box itself. If you run this code, "Filter By:" should show up at the top of the context menu.
View 1 RepliesInterface And Graphics :: Load Image And Access Its Memory Buffer
Mar 31, 2011I have some questions about bitmaps and such. I am using the IDXSurfaceFactory::LoadImage Method to load an image and now I want to access its memory buffer, so I can do some direct memory manipulation and copy the content to another buffer afterwards (no BitBlit!). I managed to successfully use LoadImage, but I have no idea how to retrieve the pointer to the memory buffer and other informations. I want to basically know everything about, how and where the image is stored in the memory buffer.
Does windows always load images as BGR regardless of its original format? if not, how can I find out if the loaded image is stored as BGR or RGB. How can I find out how many bits each color has? How can I find out if the image is stored y-reversed? And if you load an indexed png for example, with one color marked as transparent, how can I find out which color is used for transparency?
Interface And Graphics :: Drag Text From Ie8 And Drop It Onto A TextBox In VB 2008?
Feb 21, 2010I'm running Windows 7 x 64 and the latest version of VS 2008.I have spent forever trying to get the following VB6 code snippet to work in a VB 2008 Windows Forms application. The VB6 application works like a charm, even on Win 7 x64.Here is the relevant (I hope) VB6 code. It allows me to select text in IE8's browser window and then drag and drop it onto a TextBox called txtLink in a very simple VB6 application.
Code:

Interface And Graphics :: Inherited From TextBox And Auto-validating Control?
Nov 16, 2011I frequently use TextBoxes that expect date values. I do a tedious job every time to handle the Validating event. The Validation event ensures that the value is a valid date value according to the current thread's Calendar, and if so, formats the date to "dd-MM-yyyy".
I want a TextBox (e.g. DateTextBox) that automatically runs validation and formats its Text property. All I have to do is dropping it to the form.
I know I should use inheritance; but I do not know where to put the auto-validation code; and I do not know how to save the inherited class as a control in the ToolBox.

Interface And Graphics :: How To Procede With An Interface Design Approach
May 18, 2012I was wondering if I could elicit some tips on how to procede with an interface design approach.That is. What is a good way to go about establishing a "work area" where one can have multiple "floating forms" in this area.Can you have a form which occupies the entire windows desk top and the other forms "float" in this space? the "floating" forms would need to interact with each other where pressing buttons etc on them would affect other forms on the "workspace") Or what would be a good way to start accomplishing that? Or is there a better way to get the same effect?
View 4 RepliesInterface And Graphics :: Link A Class / Object To An Interface?
Apr 21, 2010I'm trying to make a .dll that contains a lot of basic functionality that a program can use. Currently i am trying to use interfaces to make a lot of this functionallity independend of the program using it but i hit a snag. The Basic idea is that a programmer will create his own object using the interface discribed in my .DLL file. Then implements those functions as he likes. He can then instanciate a controller (found in the same DLL) and sends his custom object implementing the interface to that Controller. The controller can then be started and will take over all the work. I do not know what type of object is send to the controller and idealy i want to program it in such a fashion that i shouldn't care as long as the object send implements that interface.In code I am trying to achieve the following: (quite simplyfied)
.Dll:
Code:
Public Interface MyInterface '<----Decleration of the interfaceFunction GetData() As Integer
Function SetData(Data As Integer)
end interface
[code]....
this propperly. I know that the second i set the interface adaptor in the Controller VS comes nagging that it can not be converted to a "MyInterface" Class. Obviously i am doing something wrong. I can change the datatype that the controller expects to the "MyController" type but that would completely ruin the whole idea of flexibillity. I am hoping someone sees what i am trying to do and can point out where i made the thinking error.

View 1 RepliesInterface And Graphics :: Draw On Tabpage's Graphics?
Jan 19, 2011So I decided to make my famous tile selector project, but instead of drawing in a form's graphics, do it inside a tabpage.Well, I managed to get it working, but it seems to... flicker.Normally, setting the form's DoubleBuffered property to True would help a lot there, but apparently, the tabpage has no such property.
When I invalidate the tabpage, I draw two images and fill one rectangle.Following past advice, those two images were created before, just once, and are stored in a variable so I don't create them every time I invalidate the tabpage.
