Omg means i got to create alot different class? because i still have Product hastable, catalogue hashtable, order hashtable and a few more..
So u mean create a new class for example AllData.cs
Then inside , i put the attriubutes as
public static Hashtable staffTable;
public static Hashtable productTable;
public static Hashtable orderTable;
then for the constructor
public AllData()
{
staffTable = new Hashtable();
productTable = new Hashtable();
orderTable = new Hashtable();
}
Then inside my FrmMain i create a new AllData class?
FrmMain.cs
public AllData allData;
public FrmMain()
{
allData = new AllData();
}
Then from the child form, how do i access this allData created in the FrmMain

There's no need to cretae an instance of the AllData class if the contents are static.
public static class AllData
{
public static Hashtable staffTable = new Hashtable();
public static Hashtable productTable = new Hashtable();
public static Hashtable productTable = new Hashtable();
}
You can then simply call AllData.staffTable from any class in the same namespace, or specify the namespace as well if not.

I have a combobox that is bound to the database. When I update this combobox, selected value changes.
Let's say that we have these values in combobox: AAA, BBB, CCC. The selected value is CCC. When the combobox
is updated, the selected value changes to AAA. It always changes to the first item in combobox.
Does anyone have any idea how to solve this?
Thanks

Hi, I am new to C# and im working trying some image processing, im using this bit of code to invert the pixels on an image grabbed from a video file, how do I extract the RGB values from a pixel in C# using the image buffer? Speed is of the essence...
Thanks in advance.
unsafe
{
byte* p = (byte *)(void *)pBuffer;
int nWidth = Width * 3;
for(int y = 0; y < Height; y++)
{
for(int x = 0; x < nWidth; x++ )
{
p[0] = (byte)(255-p[0]);
p++;

See this article[^], there are some examples how to extract and modify the RGB values of an image.

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.

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.

Hi..
I deployed my widows project successfully( included SQL express, .net frame work, Database file, Project files)
I installed my .exe file (setup file) on client machine(system) its installed successfully.
But when i run that application ,i got the below error:
============================
Login failed for user 'sa'. The user is not associated with a trusted SQL Server connection.
<configuration>
<system.windows.forms jitDebugging="true"/>
</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.
=============================
please help me...
thanks in advance

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.

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

I think you have to use SetLocaleInfo in kernel32.dll

Is it a question or are you demanding it? Ever heard about Google? It has many pages for you to explore[^]
By the way, don't post in multiple forums, it's rude.

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.

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
