Getting An Analog Of .NET's Bitmap Class For VB6?

Jun 22, 2011

I have a form and a custom scrollable PictureBox control (a very large PictureBox control inside another smaller PictureBox with 2 sliders to move large PictureBox inside smaller one). While scrolling large PictureBox inside smaller one the graphics that are drawn on large PictureBox get erased.I would like to use a kind of off-screen buffer technique to cache all the drawing operations and to repaint the "dirty" parts of the view if necessary. There is an example of how to do this with Bitmap class in VB.NET.Is there any analog of VB.NET's Bitmap class for Visual Basic 6?

WPF Blurry Images - Bitmap Class

Jun 12, 2009

I am using the following sample at [URL] within VB.NET. The code is shown below. I am having a problem when my application loads the CPU is pegging 50-70%. I have determined that the problem is with the Bitmap class. The OnLayoutUpdated() method is calling the InvalidateVisual() continuously. This is because some points are not returning as equal but rather, Point(0.0,-0.5). Any better implementation for pixel snapping a Bitmap image so it is not blurry?

Format Function Analog In .NET

Jan 22, 2010

There is String.Format function that is referred to in the documentation as the analog for Format function from VB6. There's also Format function from VisualBasic namespace that is provided for compatibility and basically has same powers as String.Format.Indeed, those two format dates and numbers.But VB6's function was also able to format strings:[code]String.Format is not able to do that, as far as I'm concerned, nor is the new Format. I also couldn't find any mention in the compatibility Format documentation that certain parts of VB6 functionality is lost, seems like the feature was deprecated "silently."Is there anything in the framework that can do this type of formatting?

Analog Meter In Visual Studio 2010

Sep 29, 2010

Ihave written a Visual Basic program to read serial data from an Atmel micro-controller that monitors a solar panel and a wind turbine. I have used a label box to display the digital data from the serial port and all works well.The data from the micro-controller is formatted like this (Battery voltage XX.XX) (Solar voltage XX.XX) etc.I would like to add a analog meter with a 0 to 24 scale to the program that will display the value from the micro-controller but am unable to find anything listed in the help menu of Visual Studio 2010.I have used the terms analog meter, meter and instrumentation in the help menu to look for a template but nothing comes back.Can someone either point me to a visual studio 2010 meter template and or some sample code or best of all.

How To Properly Open A Image Using Bitmap Class And Dispose It Properly

Jun 22, 2010

the following code however keeps the Image File locked until the application is running, any suggestions how to dispose it properly. (So that no handle is left open )

Things i already tried: use dispose method of bitmap <= doesnt work (need to write implementation)
Using Block also doesnt work.

Here is a short program to demonstrate my question. I just want to extraxct a rectangle bitmap from a big bitmap.Code as follows:

Private
Sub Button3_Click(ByVal sender
As System.Object,[code]....

Execution stops when hitting the Dim cloneBitmap statement, which should have created a bitmap out of the rectangle cut out.The message is:

"MissingMemeberException was unhandled.

No default member was found for type 'bitmap"

I just don't get it. Seems that the method Clone(Rectangle, PixelFormat was not found.

.net - Bitmap Generation With Dot.net And Png?

Feb 2, 2011

What resources I need to look for, to generate one png image out of three? Since there are sprite generators out there, that do not do what I want, I wanted to try by myself. The user interface should not be the problem, but i have no experience of generating bitmaps, especially those with transparent backgrounds. I will do that in .net. Let�s say I have 6 png files. I want to put them into one image, where there will be two rows of images in it, so 3 in row, 2 in height, 3*2. Every image might have a little different sizes, so i would need to fill up the space with, um, nothing..
