Your controls are poorly named, your username and password are hard coded and are the same ?
Oh, and you used = instead of ==.

I have a doubt in the enabling and disabling of menustrip items and subitems (C#.Net).
This is to be done based on user permission settings for every level and sublevel of menus.
I would like to use a recursive function to make this happen.
I am setting the userlevel(menu id) as the tag of each menustripitem.
Can anyone help me to achieve this?
This is very urgent.

sunitha

Here is how you can traverse through the menu items recursively:
foreach (ToolStripMenuItem item in menuStrip1.Items) {
process(item);
}
private void process(ToolStripMenuItem item) {
MessageBox.Show(item.Text);
if (item.DropDownItems.Count == 0) return;
foreach (ToolStripMenuItem subitem in item.DropDownItems) {
process(subitem);
}
}

Thanks Lev for your help.
But my problem is that i am using a datatable to find the user levels of the logged on user.the data retrieved from the datatble has values like :-
8(main menu item)
8.01(sub menu)
8.02
8.03
8.04
8.04.01(sub item of 8.04)
8.04.02
8.05
8.06
8.06.01(sub item of 8.06)
8.06.02
8.06.02.01(sub item of 8.06.02)
8.06.02.02
these values are the menu ids that i set in the user permission screen.
I want to iterate thru the datatable as well.getting a bit confused with all the looping.
Please help me out...........
thanks in advance

You can associate a user level (say an integer, as a Tag) with menu item, then get the current user privilege level and finally iterate through the menu (with the code I posted) and disable those items whose privilege level is higher than the current one. This way you won't have any looping problems, just go through the menus recursively

Lev,
this is the current code i am using:-
private void SetUserPermissions(int userId,int grpId)
{
DataTable objDt = objUserlBus.GetAllUserLevel(userId);
for (int i = 0; i < objDt.Rows.Count; i++)
{
foreach (ToolStripMenuItem menu in objMain.menuStrip1.Items)
{
if (objDt.Rows[i][1].ToString() == menu.Tag.ToString())
{
menu.Enabled = true;
}
EnableMenu(menu, objDt, 0);
}
}
}
private void EnableMenu(ToolStripMenuItem tm, DataTable dt, int strt)
{
try
{
foreach (ToolStripMenuItem item in tm.DropDownItems)
{
for (int i = strt; i < dt.Rows.Count; i++)
{
if (_usrGrp == 2 && item.Tag.ToString() == "7.01")
continue;
if (item.Tag.ToString() == dt.Rows[i][1].ToString())
{
item.Enabled = true;
EnableMenu(item, dt, i + 1);
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Please go thru this n verify whether i have gone wrong anywhere.

SRK

Why are you getting all the users permissions? There is only one user that works with the program instance. It is enough to get current user's permission level, and then iterate through the menus, tuning it as you need

I am getting only the currently logged in user's permissions into the datatable,by passing his userid.I think you got confused by then name of the function.
SRK

Well, I see,
You are storing all the menu IDs applicable to the user permissions in a DB and then enable/disable the menu items with this IDs, am I right?
I don't think this is efficient, you are storing a lot of redundant data, try to do it the way I suggested. Do not keep menu IDs in the DB, instead keep the user privilege level, associate it with each menu item. This way you will get just the user permissions level from db (an integer for example) and compare it with the level associated with the menu item. See my previous post.
Regards,
Lev

I dont understand how the data will b eredundant,as the fields in the usrlvlmas table are usr_id n menu_id.
Each time new permissions are set for the user,all the existing levels for that user are deleted and only new ones are updated.
Anyway let me have a try again.

The key of my suggested approach is having general permission groups (levels, like admin, power user, restricted user) and not individual permissions for each and every user, that's generally the way it is being done (e.g. in Asp.Net membership providers).

Hi friends,
plz any one reply me how can we change datagridview row's background color in runtime.
|
|
|
|
|
If this is not an ASP.NET question, surely the control has a Background or BackgroundColor property ? If not, you'd have to owner draw it, but that would seem odd to me.

DataGridViewCellStyle style = new DataGridViewCellStyle();
style.BackColor = Color.Blue;
this.dataGridView1.RowsDefaultCellStyle = style;
|
|

Do it as
gridviewID.BackColor = "ffffff";
Cheers!!

I have created a C# Windows application in .NET 3.5, it runs the powerpoint slideshow and closes all the existing slideshows and should only run the new .ppt application.
In C# when I run this application with putting breakpoints it runs fine and gives no error.
But when I run it without breakpoint and say Ctrl+F5 then it throws the exception
Retrieving the COM class factory for component with CLSID {91493441-5A91-11CF-8700-00AA0060263B} failed due to the following error: 800706ba.
I have followed these links

http://blog.crowe.co.nz/archive/2006/03/02/589.aspx[^]
But got no help.
Can please anybody help me?
Thanks in advance,

Generally this means that the pause created by the breakpoint, fixes a race condition. Try putting a sleep before the code in question, if that fixes it, try to work out what your race condition is.

I've been been tasked redevelop a bespoke application that's showing its age, it's functionally very rich but it's UI is circa Windows 3.0 and it's internal architecture makes it costly to maintain. It's written in C/MFC with a proprietary "database", it's genesis goes back to the late '80's.
The stakeholders agree that the application cries out for a dock panel interface a'la Visual Studio etc. I'd really appreciate knowing what products folks have used to implement a dock panel user interface and their experiences in doing so - rolling our own is not an option we would want to persue.
I've identified five potential sources for a dock panel control, please tell me of any others. My client is a non-for-profit so the budget is limited, but it's not zero. Major considerations include access to source (free, escrow or pay (within reason) are all acceptable), robustness (even at the expense of some functionality), support costs & quality and documentation.
AvalonDock - open source, free, lives at Codeplex, it's a "vanilla" dock panel control, it's the successor of http://www.codeproject.com/KB/WPF/WPFdockinglib.aspx[^]
Nevron UI for .NET - proprietary, costs US$169, this library includes other stuff beside Dock Panel, which has some attractions
JastDev Docking Control - proprietary, costs US$78, supports XAML Browser Application development which has some appeal, does not include much other than the dock panel control.
Actipro - Docking & MDI Control - costs US$149, includes a fairly extensive set of atomic controls. Actipro have a bundle for US$499, that adds ribbons, navigation, property grid etc, this too has some appeal.
Dock Panel Suite - open source, free, lives at Source Forge, it's a vanilla WinForms dock panel control (I missed this one in my original post, thanks to John Simmons for reminding me of its existence)

I guess a big question is, do you want to use WPF, or not / At least one of these seems to be WPF ? Are they all ?

You're right they're all WPF. Its what my search turned up.
Actipro has a Windows Forms Dock Panel in a suite with Tab Strips, Navigation etc.
There were some el cheapo WinForms controls which I rejected, some were moribund, i.e. they'd not been updated for years, or their mail addresses bounced or their forums had not had a post for 12 months or more etc.
I'm not enamored with WPF, because I'm not convinced that XAML is an efficient declarative language. Seems to me that there are too many ways of doing the same thing and no clear guidelines on what to use when, but I really need to use it anger to make a rightful judgement. I originally thought C was rubbish when I was writing PDP-11 assembler, so I don't take much notice of what I think.
Office 2007 is an influence, client recently upgraded to it, being who/what they are they get academic pricing. Apparently the users wanted their menu's back but after a few weeks they all got to love the ribbons etc, now they complain about Outlook not having ribbons & orbs.
The users don't know/care if its WPF, XYZ or �(, but they've seen things like the Health Care facade that MS did in the UK and they've indicated like some of that. Also given that the current system was bleeding edge when it was developed nearly 20 years ago, they're of the view that if they do they same again then they'll get 20 years out of any new system.
So do I want to use WPF, probably not, but do I expect to use it - probably. I may need to find someone with WPF skills and a heart of gold, i.e. willing to work long hours over a couple of years for shirt buttons.

We're currently using DockPanel Suite[^]. It does not use WPF.
