GDI+ can handle this for you, though i'm not sure how well it will perform. There is a function in the Graphics class called DrawImage. It has about 25+ overloads and one of them accepts arguments for a source bitmap for which you can provide co-ordinates of the part of the image you want, you...
My two cents.... If I had to make a choice between VB.Net and C# it would be VB.Net all the way and here's why.... Why would you want to go to the trouble of learning a second rate C style language like C# when you could just go ahead and learn the real thing and start programming in C++. Im my...
This may be a little to generic and some futher processing may be neccesary however if you override the wndproc and intercept the WM_COMMAND message and place the code to change the text there. I have no doubt that you will have to either use the HIWORD of the wParam to determine which control...
Oh ok, think I know what happening here. Turns out ot be a common problem with click once. Try going the properties page of the project. Application files button-> and change from pre-requisite to 'Include' for the so called missing files and re-publish.
Well looking at the error message it sounds like a glitch and a file has been corrupted somewhere in the GAC or possibly it was never there to start with? Have you tried re-installing the appropriate version of the framework?
Probably not what you are going to hear but a re-design of your form is 'the best' way A lower quality image will reduce load time but I think you'll find that your going to need to break that huge form down into smaller chunks either by using more sub-forms or potentially some panels that you...
That is completely and utterly not true. You will only take a performance hit from .Net on startup whilst the base class libraries are loaded along with the CLR and any other dependancies that you app may have. However all programs are pretty much subject to that.
The machine instruction that...
Something like this.. using a bit of reflection.
Imports System.Reflection
Dim frm As Form = DirectCast(Activator.CreateInstance(Type.GetType("yourApplication.someFormName") ), Form)
frm.Show()
It would't be easy. But it's totally possible, it's just a collection based control with a few bells and whistles. I'm not sure how best to advise you as I don't know how much time you want to spend on this. I'm happy to help you make one but it will take a while.
dim img as new bitmap(filename)
dim img2 as new bitmap(img, mybutton.width, mybutton.height)
mybutton.Image = img2
Should be...
dim img as new bitmap(filename)
mybutton.BackgroundImageLayout = ImageLayout.Stretch
mybutton.BackgroundImage = img
An .ldb file is created everytime you open an access database. It can't be deleted until you close the access database or close the process that created it.
I doubt it, seeing as the bindingsource.EndEdit calls the CurrencyManagers.EndEdit and this is an implementation of IEditableObject. However the Datarow's EndEdit is not an implementation of this interface. So therefore there must be some plumbing somewhere to pass the info along that changes...
The Dataset doesn't care how much you edit a datarow. The datarow, datatable and dataset only care when you've finished editing a row. This is when you would usually call DataRow.EndEdit, or it is called implicitly when you cycle to a different row using the BindingNavigator. To affect a change...
VB.Net has the capability of calling any and all API's as has c#. If it couldn't the framework wouldn't work at all seeing as just about everything you do in .Net will eventually filter down to some kind of interop.
title here is, as you probably know, is a pointer to an ANSI string. I'm not sure how the framework will handle this probably using WideCharToMultiByte. However it should all be done for you. Passing a .Net string by reference should produce the desired result seeing as it's only a pointer a...
