If you want to get the string
"this is not a valid transaction." from the response,you can use this:
str.Substring(str.LastIndexOf("|")+1,str.Length-(str.LastIndexOf("|")+1))
where str="0|R002|this is not a valid transaction."

This is the most frequent programming error of all times: You used the assignment operator (=) instead of the comparison operator (==) in your if statement.
Use if (T1.Text == "admin" && T2.Text == "admin") instead, and everything is fine...

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.

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.
