Datagridview sort by 2 Column??? [modified] - C# Discussion Boards

I think the biggest problem a lot of password generating programs have is that they don't guarantee a strong password. While choosing random characters from a set of predifined values might get you very diversive password, it doesn't mean it always will. So despite using long password, you could still end up with weak ones like 'ifdhgkfsd'. There should be some code to check, if teh generated password meets some special requirements, and possibly do some adjustments. A good example for this is the built-in membership provider for ASP.NET 2.0, which requires you to have at least one non-alphanumerical character in your password. Then again it's not a generator tool, it just checks a given password. I don't mean to stay you need these precautions in every case, however I do mean you should find (or possible write) code that allows usage of similiar features. For example:

public string GetPassword(int length, int minUppercaseLetterCount, int minNumberCount, int minNonAlphanumericalCount)
{
//your code here Smile | :)

}

Obviously, for simple passwords you would use it like GetPassword(5, 0, 0, 0). And if you ever need strong passwords you can still reuse this function.

I think this smells like an article Smile | :)

. Someone should write it. Or maybe I will Big Grin | :-D

i thought about this problem. SO i took the function that GUFFA provided and i am trying to implement it in a way to force it to generate some strong password with at least 2 digits in it.

Obviously by writing an article I also meant writing the code, since the article itself would be pretty much the code itself, with some explanation Smile | :)

You have two options

1 - buy/download a charting control
2 - write the code to draw a chart

Once you have your chart, on a bitmap, you can either draw it in your paint event, or use a picture box

hi,

i have a problem with datagridview sort methode.
i doono whether i can sort datagridview by 2 Columns. there's example

username--------actionType--------filename
user1-----------download----------picture1.tiff
----------------upload------------picture2.jpg
----------------upload------------picture3.tiff
user3-----------download----------file1.txt
----------------download----------file2.txt
admin1----------upload -----------config.cfg
----------------download----------db1.mdb

so there i wanna sort the table by 'filename' and 'username', i mean the order of username Column should not change but the order of 'filename' and the association of 'username' and 'filename' should not change neither.
just like the effect in slq 'order by username, filename'

has anyone a idea?

regards

faye

Use a BindingSource to bind your table to the DataGridView, then use the BindingSource's Sort property to specify the columns and directions to sort. E.g.:

bindingSource.Sort = "username, filename";

You can also specify the direction of the sort, e.g.:

bindingSource.Sort = "username ASC, filename DESC";

You came to the right place. Big Grin | :-D

On these forums you'll find some of the weirdest, rarest, and most funniest programming problems you'll ever meet in your life. Many are high level, but still many are from beginners. Just wait till a question is posted, then try t o think of an answer. Make a dummy project to try out your solutions. When someone does answer and it works compare your solution to his. After sometime you'll know the guys who provide what is usually a "Best Practice" answers from the guys who just screw up thing like me. Stick to them, they will help a lot.

BTW:
If you think your answer is quite good enough why not posting it if no one did? Maybe you'd get sarcasm in the beginning, but don't let that depress you. You'll get a grasp on it soon.

How can I open a windows service when the service starts.
I tried to open it, it's opened but the controls don't appear and then immediately it becomes "not responding".(Interactive with desktop is checked)

Re: Windows Form from windows service

You can't just double click on the service's exe file for it to run. Either use he Services applet from the Administrative tools, or in your code use the ServiceController class.

Dear All,
I am using XFS API to send commands to ATMs. For example If I want to get the information of Receipt Printer, I am calling the following function..

public class XFS
{
[DllImport(@"msxfs.dll")]
public static extern int WFSGetInfo(ushort SPIHandle, uint Category, IntPtr QueryDetails, uint TimeOut, ref IntPtr result);
}

I want to know that what value of SPIHandle I have to pass.

Really need help guys!! Am just a newby in .Net programming, i am using visual studio 2005 and studying C# programming language. I am building a utility software that would need to be opened by clicking or double-clicking the file built by my application using its own file extensions, much like zip files in windows explorer loading on WinZip etc... Really need help... Please anyone..Sample C# 2005 codes would be very much appreciated. Thank you!!!

args is the parameter list. if you open app through file the first parameter is the file name.. then you can do whatever you want with it..

"args is the parameter list. if you open app through file the first parameter is the file name.. then you can do whatever you want with it.. "

-what do you mean, i'm sorry i don't get it..in vs 2005 these lines are included in the Program.cs file, isn't it? These are my codes in my main form using the Form_Load Event.

RegistryKey rk = Registry.ClassesRoot.CreateSubKey(".sis",RegistryKeyPermissionCheck.ReadWriteSubTree);
rk.SetValue("Content Type", "application/x-sis");
rk.SetValue("PerceivedType", "file collections");
rk.SetValue("", "SIS");
rk.CreateSubKey("OpenWithList");
RegistryKey rk2 = Registry.ClassesRoot.CreateSubKey("SIS", RegistryKeyPermissionCheck.ReadWriteSubTree);
rk2.SetValue("", "SIS File");
rk2.CreateSubKey("DefaultIcon",RegistryKeyPermissionCheck.ReadWriteSubTree);
try
{
RegistryKey rk3 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("DefaultIcon", true);
rk3.SetValue("", "C:/sis.ico");
RegistryKey rk4 = Registry.ClassesRoot.OpenSubKey("SIS", true);
rk4.CreateSubKey("shell", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk5 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true);
rk5.CreateSubKey("open", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk51 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open", true);
rk51.SetValue("", "Open with &SIS");
RegistryKey rk6 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open",true);
rk6.CreateSubKey("command", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rk66 = Registry.ClassesRoot.OpenSubKey("SIS", true).OpenSubKey("shell", true).OpenSubKey("open", true).OpenSubKey("command", true);
rk66.SetValue("", "C:/SIS.exe");
RegistryKey rkapp = Registry.ClassesRoot.OpenSubKey("Applications", true);
rkapp.CreateSubKey("SIS.exe", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp2 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true);
rkapp2.CreateSubKey("shell", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp3 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell",true);
rkapp3.CreateSubKey("open", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp31 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open", true);
rkapp31.SetValue("", "Open with &SIS");
RegistryKey rkapp4 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open",true);
rkapp4.CreateSubKey("command", RegistryKeyPermissionCheck.ReadWriteSubTree);
RegistryKey rkapp41 = Registry.ClassesRoot.OpenSubKey("Applications", true).OpenSubKey("SIS.exe", true).OpenSubKey("shell", true).OpenSubKey("open", true).OpenSubKey("command",true);
rkapp41.SetValue("", "C:/SIS.exe");

-what these lines of code do are adding entries in the Windows Registry such as default icons, type of file, etc. I can't seem to connect them to be default to run on my application as it prompts access denied message and worst, i don't know how i would activate my application and loading the clicked or double-clicked file onto it.... PLEASE HELP ME, WHAT WOULD I DO???
