Re: How to get a RGB values from an image buffer?

This is how you get the color components of a pixel, specified by the x and y coordinates:

byte* p = (byte *)(void *)pBuffer;
p += (x + y * Width) * 3;
byte r = *(p++);
byte g = *(p++);
byte b = *p;

If you increase the pointer for the last component also, it will point to the next pixel. This is very useful if you access the pixels in sequence, as you don't have to calculate a new address for each pixel.

Despite everything, the person most likely to be fooling you next is yourself.

Creating DataView filter ...

Hi All,

I have a field that I which to filter on using the Contains operator but currently its throwing a wobbly. Can anyone advise? Is this even a legal operator to use in the DataView?

filter = filter + "and fileName Contains '" + _freetext.ToString() + "'";

fileName is of type string. For instance the _freetext maybe something like "day" so things like "daytime", "sunday" would both be included.

Thanks in advance.

Login failed for user 'sa'. The user is not associated with a trusted SQL Server connection.

<configuration>

When JIT debugging is enabled any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

How did you get this far and not know that the login you use needs to match the SQL Server installation you're using ? Also, why is your user logging in as SA ?

You need to create a user with just the permissions they need, and make sure that your connection string and the SQL Server instance you're using, match in terms of username/password/etc.

Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.

You need to create your own culture and set the separator for that.

I think you have to use SetLocaleInfo in kernel32.dll

You need to add a reference to a dll that contains FolderParam class.

You are writing a piece of code which uses folderparam class and you don't know it comes from? In that case you even won't know what the class is for!

1.Check your spelling before you make a post.

2.If you got code from Google, then Google can tell name of the dll for that class. If you think that I know all dll's and classes that they contain by heart, you are mistaken.

NumericUpDown in hexadecimal mode bug

Schokoolero5-Jul-08 0:17

Schokoolero

5-Jul-08 0:17

When I use a NumericUpDown with Hexadecimal=false and a number that is too large or to small is entered, it is set to the corresponding limit.
With Hexadecimal=true however, the value is reset to the previous, correct, value, when a value too large or too small is entered.

I have tried to intercept the ValueChanged and various other events to get the same effect as with Hexadecimal=false, but there seems to be no situation in which I can read the entered value instead of the already reset value and adjust it manually.

Does anybody know a solution to this problem?

Thanks

Thanks for the reply!

I tried Validating, but that is only thrown, when the NumericUpDown gets the focus or looses it and in similar situations. It doesn't seem to be thrown right before the value is changed wrongly.

I also tried KeyDown, but wasn't able to intercept the value the NumericUpDown should take after the Key was pressed if there was no maximum and exchange it for the real value.

I solved my problem by enhancing a TextBox to take only hexadecimal numbers, adding a minimum and maximum etc. to it.

up till now users don't have IP addresses, computers do.
