If all of your checkboxes are located in a container control (panel, groupbox) or if they are the only controls on your form then you could use a foreach statement.
foreach(Control aControl in form1.controls)
{
CheckBox aCheckBox = (CheckBox) aControl;
aCheckBox.Enabled = true;
}
I did not test the above code. It's just off the top of my head.
You could also create and arraylist of checkboxes and interate through then the same way.

You could put all CheckBoxes into an array and iterate over it:
CheckBox[] _allCheckBoxes;
_allCheckBoxes = new CheckBox[31];
_allCheckBoxes[0] = CheckBox1;
_allCheckBoxes[1] = CheckBox2;
foreach (CheckBox cb in _allCheckBoxes)
cb.Enabled = true;

Are you sure thats possible?
When I try to do it it wont work, it give's me A LOT of errors and all kinds of warnings.

Well...
yes Im sure  .
If you want I can mail you a small sample.

Thanks for the suggestions I will try them out

Is it possible to do it with menuitems?
And sure, mail the sample to me...

Thanks for all the suggestions I managed to do do it by the following:
TCheckBox *ChkBx[34];
ChkBx[0]=CheckBox1; //Declaring them all once into an array
ChkBx[1]=CheckBox2;
...
ChkBx[33]=CheckBox33;
for(int i=0;i!=4;i++)
{
ChkBx[i]->Checked=true;
}
I also used this concept with Graph Line Series ie.
TChartSeries *Ser[4];
...
Thanks Again

Hello!
Ihave extendended the ShellLib (from arikp's article) to support the IEnumIDList interface. Here is the code:
<br />
[ComImport]<br />
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]<br />
[Guid("000214F2-0000-0000-C000-000000000046")]<br />
public interface IEnumIDList<br />
{<br />
[PreserveSig]<br />
Int32 Clone(out IntPtr ppenum);<br />
<br />
[PreserveSig]<br />
Int32 Next(UInt32 celt, <br />
[MarshalAs(UnmanagedType.LPArray, SizeParamIndex=0)]<br />
out IntPtr[] rgelt,<br />
out UInt32 pceltFetched<br />
);<br />
<br />
[PreserveSig]<br />
Int32 Reset();<br />
<br />
[PreserveSig]<br />
Int32 Skip(UInt32 celt);<br />
}<br />
and I get an instance of this interface using:
<br />
public static IEnumIDList GetEnumIDList(IntPtr ptrEnumIDList)<br />
{<br />
System.Type shellEnumIDListType = System.Type.GetType("ShellLib.IEnumIDList");<br />
Object obj = Marshal.GetTypedObjectForIUnknown(ptrEnumIDList, shellEnumIDListType);<br />
IEnumIDList RetVal = (IEnumIDList)obj;<br />
return RetVal;<br />
}<br />
If I try this code:
<br />
UInt32 celt = 10;<br />
IntPtr[] ptrList = new IntPtr[celt];<br />
UInt32 count;<br />
EnumIDList.Next(celt, out ptrList, out count)<br />
The Shell dosen't fill the ptrList and count is 0. The IShellFolder is the Desktop folder.
<br />
IntPtr ptrFoldersList;<br />
iDesktopFolder.EnumObjects(this.Handle, (Int32)ShellApi.SHCONTF.SHCONTF_FOLDERS | (Int32)ShellApi.SHCONTF.SHCONTF_STORAGE, out ptrFoldersList);<br />
If you need any details please let me know. I don't really see what I did wrong... (maybe I'm dumb ).
Thank you!

When deriving your interface from IUnknown (which is what happens in the CLR when you specify ComInterfaceType.InterfaceIsIUnknown for the InterfaceTypeAttribute on the interface), the methods must be in the ordered defined - not the order documented. This means the interface should be defined as:
[Guid("000214F2-0000-0000-C000-000000000046"),
InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
ComImport]
public interface IEnumIDList
{
[PreserveSig] int Next(ulong celt, IntPtr[] rgelt, out ulong pceltFetched);
[PreserveSig] int Skip(ulong celt);
[PreserveSig] int Reset();
[PreserveSig] int Clone(out IEnumIDList ppenum);
}This is also true of ComInterfaceType.InterfaceIsDual. If you use only ComInterfaceType.InterfaceIsIDispatch then you must have attribute your methods and properties with the correct DispIdAttribute values.

It works now! Thank you very much. I'll keep that in mind next time.
|
|
|
|
|
Or not... All I get is the same folder that called EnumObjects. pceltFetched == 1 in all the situations and the rgelt[0] points to the parents PIDL. Very strange... Any explications would be very helpful. Thank you.

I would have to see more of your implementation to know how you're using it.

The code that uses those functions:
<br />

{<br />
DummyTreeNode RootNode;<br />
IntPtr ptrRootFolder;<br />
ShellApi.SHGetFolderLocation(this.Handle, (short)ShellApi.CSIDL.CSIDL_DRIVES, IntPtr.Zero, 0, out ptrRootFolder);<br />
IShellFolder iRootFolder= ShellFunctions.GetShellFolder(ptrRootFolder);<br />
IntPtr ptrFoldersList;<br />
<br />
ShellApi.STRRET iInfo;<br />
iRootFolder.EnumObjects(this.Handle, (Int32)ShellApi.SHCONTF.SHCONTF_FOLDERS | (Int32)ShellApi.SHCONTF.SHCONTF_NONFOLDERS, out ptrFoldersList);<br />
IEnumIDList iFoldersList = ShellFunctions.GetEnumIDList(ptrFoldersList);<br />
RootNode = (DummyTreeNode)Nodes[0];<br />
RootNode.AddSubFolders(iFoldersList);<br />
}<br />
<br />
public void AddSubFolders(IEnumIDList EnumIDList)<br />
{<br />
try<br />
{<br />
String[] SubFolders = ShellFunctions.GetSubFolders(EnumIDList);<br />
for (int i = 0; i < SubFolders.Length; i++)<br />
{<br />
this.Nodes.Add(new DummyTreeNode(SubFolders[i]));<br />
}<br />
<br />
}<br />
catch (Exception e)<br />
{<br />
System.Windows.Forms.MessageBox.Show(e.Message);<br />
}<br />
}<br />
<br />
DummyTreeNode is a class that inherits from TreeNode class. Nodes[0] exists and it is the iRootFolder display name. (These are beta functions and are harder to read... sorry for that)
PS: I get an ExecutionEngineException in GetShellFolder(ptrRootFolder)...
|
|
|
|
|
And ExecutionEngineException is hardly a small matter for a "PS" - that's about the worst exception the CLR can throw, which indicates a problem with the CLR itself. I also don't know what GetShellFolder does.
You might consider running a repair on the .NET Framework from the Add/Remove Programs control panel applet.

It was the first time i used GetShellFolder (until now I used SHGetDesktopFolder because I wanted iRootFolder to be the Desktop folder). Thank you for the support!

I am dumb! It works now... I forgot to get the IShellFolder structure from the PIDL with SHBindToParent()...

Hello!!
Im trying to remove all html tags except some tags like <b> and <i>.
I did a nonCapturing Group but this don't work.
Alternate bar | suppose to match left most option....

A non-capturing group doesn't mean that the pattern isn't matched. It only means that the match does not create a group.
---
b { font-weight: normal; }

Your right... I corrected the problem in another way.
Thanks

My Question is:
Because the picture is exsist in my "image\" directory,but they can't show!
(1)Whether I must write some codes in webform.aspx.cs?

hi all
is there any way in C# makes me catch the hotkey (win+D) and override this message to do my own
thx all
|
|
|
|
|
yeah there is, i found this awesome library on planet-source-code.com. I dont exactly remeber the link but run a search for Hotkey and Hot Key and the result will show up. Its really easy use. Use it and save yourself the trouble of reinventing the wheel.
