Interface And Graphics :: Popup Selection From Dynamic List?
Aug 8, 2008
Is 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?
I have a grid and i have a popup contextmenu. My problem is the contextmenu is popup in the same screen location, and not on the location of the mouse.
I have an AppBar application that I've added a few drop down menu items and context menus to, but each and every time I try to access the menus, they appear outside of the form. This is what's happening with the drop down menu button I've added to my status strip, and context menus show up on the right side as well.
what I mean, every full-featured program has one. Tools > Options brings it up in Firefox. First off, I've looked for tutorials on making these and can't find them anywhere, does anybody have any links? Second, I'm making mine with a TreeView and panels. The problem is designing this thing with all of these overlapping panels! It's crazy. So, how do you easily make an options menu like Firefox where clicking on different tabs brings up different data options?
I already have one year experienced in c++, and built many private applications.My question is simple to ask, and simple to answer I think.When I select an item in a listview, I want the full item to be selected. Now only the TEXT in the listview item is selected. I've made a picture to clearify my problem.The picture in the link below is splitted up in two pictures. It shows what I currently have, and what I want (my aim)
How would you add a Dynamic Contextmenustrip to your form and how would you add the items to the contextmenustrip. Also when adding the items to the menustrip is it possible to give them names and text dynamically if so how?
I am need to drag drop listboxes with connection line in vb.net. If the listbox move then connection line should also move. I have attached picture as wel
I would like to build a line chart which can redraw or change during a period of time with dynamic data. So that the x, y axis will change if out of range. The graph may be somehow similar to Matlab. I am using vs2005.
I know the question is a little choppy and perhaps misleading,but I have a gridview with dropdownlists on the rows. I created an AddHandler and a Delegate for the SelectedIndexChanged and it gets to the sub. Here is the code for that:
AddHandler ddlmgr.SelectedIndexChanged, AddressOf ddlmgr_SelectedIndexChanged Public Delegate Sub DropDownList_SelectedIndexChanged(ByVal sender As Object, ByVal e As DropDownList_SelectedIndexChanged)
Protected Sub ddlmgr_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
End Sub How can i get the row's Id if GridView_RowCommand is not called?
I have got a problem. Here is my problem: I have a CheckListbox and in that checklistbox i insert some checkboxes. But those checkboxes should have different colors dependin on the condition.
Im working on a project that needs to print a report of one client.Everything went smooth untill i came across my multiline input text data.When i display it in the PrintPagePreview the text go's outside my page. Even when im printing it only the halve of my text is displayed. I googled and looked everywhere but i can't get a clear fix for it.
I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
drawing text on a window which is not the current form's window.I remember doing this in Win32 api with getwindowdc(handle) to obtain a DC for the Window, then textout() on the DC.
I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.
Ok, I want to create a class that will handle a special rectangle graphic.In my form, I want to have two of these special rectangles. So, basically, I need two instances of that class in my form, right?I manage to initialize two, alright. But, how exactly am I supposed tomanage drawing/graphics etc in a class, and the results to be displayed in my form?
I 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?
I'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.
Is this where i would post a picture of my interface and get feedback on changes for easier use? If not is there someplace on this forum or any other forum to do this?
So 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.
I load my picturebox with a jpeg. If I put my DrawObjects() sub into picturebox paint event.When ever a picturebox.refresh or picturebox.visible = true (vb.net seems to draw my DrawObjects() first, then load the jpeg Image over my drawing - erasing drawing) Is there a way to get the picturebox to redraw the jpg image first then draw on it, in picturebox paint event?
We have a GUI that displays a radio selection box (3 options) that are the three sites where our hospitals are. We need to dropdown located on the form to fill with only the locations based on the selected radio option.
Here is the code behind we have so far (sorry, VB)
[Code]....
For the record the Location dropdown is currently databound but its a static SELECT statement which brings us all the locations but we'd prefer it to be cleaner if it only returned the locations based on Site. We are using Visual Basic 2008 Express Edition for development.
I have four comboboxes in my Ist form related to course as.c_type,c_stream,c_major,c_nature.......combobox c_type contains the type of courses like degree,diploma, PG etc,similarly "c_stream" contains stream like engg,medical etc. further c_major contains all courses like computer engg(CE),mechnical(ME), physiotherapy etc. and last c_nature has course nature whether regular or private or distance.Now situation is when i select diploma from c_type, corresponding options must be populate in c_stream like engg. And now when i select engg., CE or ME must be there in c_major combobox .Same is for C_nature.The all 4 combobox must show "please select" text on form load event..i also have 2nd form where i have same combobxs. so is there any way to call the same code without again writing that to 2nd form.
