Hi,
What might be the causes of Access Violation exception while calling a method of a c++ dll from C#.

Why don't you provide some more details

Hi,
I need to upload file in a folder at FTP server,i have already posted this but i need a coding guide not a software for this.
The code i used is,
txtfilurl.Text = FileUpload1.PostedFile.FileName;
FileInfo filename = new FileInfo(txtfilurl.Text);
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(txtaddr.Text + "/" + filename.Name);
request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(txtuser.Text, txtpass.Text);
request.KeepAlive = false;
request.UseBinary = true;
Stream ftpstream = request.GetRequestStream();//--->This line shows the error
FileStream file = File.OpenRead(txtfilurl.Text);
int len = 1024;
byte[] buff = new byte[len];
int bytesread = 0;
do
{
bytesread = file.Read(buff, 0, len);
ftpstream.Write(buff, 0, bytesread);
}
while (bytesread != 0);
file.Close();
ftpstream.Close();
Error msg is:Web exception
The remote server returned an error: (550) File unavailable (e.g., file not found, no access).

Judging by the error, you gave an invalid path to the file on the FTP server. It's impossible to tell just by looking at the code.
|
|
|
|
|
Hi,
Thanx for replying,i am sure that i have given the right path i have checked many times.
Is there is any other way to do the upload.
|
|
|
|
|
In that case, I'd use something like EtheReal to watch the TCP traffic coming out of your machine and see what the FtpWebRequest is actually sending to the FTP server.

1)A program returns a long string like the strings below, delimited by pipe character, where errorcode, error details, and long reason are stored. Write c# code to get the long code out of the response received.
0|R002|this is not a valid transaction.
1|R003|the card has expired.
2|R004|card code is invalid.
2)
a. table tblcode has codes like the following
CUPA0001
CNOI0001
CUPA0002
CNOI0003
CDEL0001
b. objective is to get the next code given the three digits unique code.e.g. Given DEL, NOI, UPA the next code is CDEL0002, CNOI0004, and CUPA0003
write a function in sql server to achieve this .the function will get input parameter as, city code in 3 characters e.g. DEL,NOI,UPA and should return the next code as per logic above

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.
regards,
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
