Hello,
How can I see the source code for an IRR function in Microsoft.VisualBasic namespace using the Reflector tool, any ideas?
Thank you.

Hi!
Here's the C# version of the code:
public static double IRR(ref double[] ValueArray, [Optional] double Guess )
{
double num5;
double num6;
int num11;
try
{
num11 = ValueArray.GetUpperBound(0);
}
catch (Exception)
{
throw new ArgumentException(Utils.GetResourceString("Argument_InvalidValue1", "ValueArray"));
}
... and so on...
}Start Reflector, open the file Microsoft.VisualBasic.dll (that's the assembly IRR is contained in, just read the documentation on the function to retrieve this information).
Navigate to the class Microsoft.VisualBasic.Financial and there you'll find IRR. Double click the function to see the decompiler window.
Regards,
mav

I can't navigate within the reflector to the Microsoft.VisualBasic.dll.
All I got is System.System.dll.Microsoft.VisualBasic etc.... How can I open Microsoft.VisualBasic.dll? How can I load assembly into the reflector?
Would you be able to post all of the code. Thank you very much.

My first choice would be to try File/Open, then go find the Microsoft.VisualBasic.dll file. A simple search of the hard drive for the filename reveals that it's in C:\WINDOWS\Microsoft.NET\Framework\version.

I found the way of looking up the code using Reflector.
You must go to File -> Cache..
Load the required assembly, and then access the IRR code.
I did add the reference to that assembly, I just really wanted to see how the method was implemented.
Thank you all!

If a user logs on such as "insert user name here" i want to play a sound "insert sound 1 here", but if a different user logs on, i want to play a different sound.
So can i check what user has loged on? or if a specific user has loged on?

Have you tried using System.Security.Principal.WindowsIdentity.GetCurrent() to return the WindowsIdentity for the current user? Then, use the Name property to get the user name. Then you can play the appropriate sound for that person.

I've made a class containing an algorithm to make a query from MS Access. From a window form, i call to the class to make use of the method. In the first run, the result returns quite fast (130 records). But on any query after the first one, it runs VERY slowly. With only 130 records, it shouldn't be that slow. Is it because of MS Access or VS.NET 2005 Beta 2? I've tried to dispose all resources but it still doesn't work. What's going on here?

Dear all,
I have created an imagelist at runtime and am trying to fill it with images created at runtime.These images are of type Bitmap and are created based on the info from database.
Everything works fine but the problem is all the images in the imagelist are of the same color whereas it has to be be of different colors...here is my code...Any help would be appreciated.
/***********************************************************************************
iList myImageList;
FormLoad()
{
CreateImage();
myImageList = new ImageList();
if (myList.Count != 0)
{
foreach(Bitmap ic in myList)
{
myImageList.Images.Add(ic);
}
}
foreach (TwigCategory cat in m_TwigCategories)
{
this.cmb_CATEGORY.ImageList = myImageList;
Item = new ComboBoxExItem(cat.Description,0, cat.ID);
this.cmb_CATEGORY.Items.Add(Item);
}
}
private void CreateImage()
{
foreach (TwigCategory cat in m_TwigCategories)
{
Color color = ConvertRGB2Color((int)cat.RGB);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(16, 16);
for (int x = 0; x < bmp.Height; ++x)
for (int y = 0; y < bmp.Width; ++y)
bmp.SetPixel(x, y, color);
for (int x = 0; x < bmp.Height; ++x)
bmp.SetPixel(x, x, color);
myList.Add(image);
}
m_TwigCategories.Reset();
}
private Color ConvertRGB2Color(int rgb)
{
int red = (int)rgb & 255;
int green = (int)((int)rgb / 256)& 255;
int blue = (int)((int)rgb / 65536) & 255;
Color color = Color.FromArgb(255, red, green, blue);
return color;
}

Could we get some sample rgb values for the ConvertRGB2Color method? Are you sure that your bit-twiddling is correct there?

Hi,
I have got the solution .I made a very stupid mistake in loading the images to the imagelist.Here is the complete solution...
This code could be useful to those who want to create a dynamic image programatically and add it to the imagelist.
I fetch the colors from the database and create a square image and fill it with the database color and display in the combobox as images.The colors are stored in the database as integers.
Formload():
CreateImage();
myImageList = new ImageList();
if (myList.Count != 0)
{
foreach(Bitmap ic in myList)
{
myImageList.Images.Add(ic);
}
}
int k = 0;
foreach (TwigCategory cat in m_TwigCategories)
{
this.cmb_CATEGORY.ImageList = myImageList;
Item = new ComboBoxExItem(cat.Description,k, cat.ID);
this.cmb_CATEGORY.Items.Add(Item);
k += 1;
}
private void CreateImage()
{
foreach (TwigCategory cat in m_TwigCategories)
{
Color color = new Color();
color = Color.FromArgb((int)cat.RGB);
System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(16, 16, PixelFormat.Format32bppArgb);
bmp.MakeTransparent(Color.Transparent);
int i, j;
for (i = 0; i < bmp.Width; i++)
{
for (j = 0; j < bmp.Height; j++)
{
Color pixelColor = bmp.GetPixel(i, j);
int r = color.R; // the Red component
int b = color.B; // the Blue component
int g = color.G;
Color newColor = Color.FromArgb(r, g, b);
bmp.SetPixel(i, j, newColor);
}
}
myList.Add(bmp);
}
m_TwigCategories.Reset();
}

how can draw a my custom scrollbar so to draw my own button up and down, customize the central scroll button, and the back bar?
|
|

|

My guess would be to override the OnPaint method just like every other control.

|
|
|
|
|
|
When you searc a file in Windows Explorer on XP, You see an animation at left side of window (if u havent turned it off before) sometimes a dog, some times a magician named MERLIN. I need that animation files.
|
|
|
|

Has anyone experienced lockup issues when adding animated gifs to a typical Windows Form? I have a simple form with a picureBox panel. When I add an animated gif, the environment locks up and I have to kill it through task manager.
Is this a known bug or is there a workaround?
Thanks in advance for any info.
