Hashtable hashTable = new Hashtable();
hashTable.Add("1", "AAA");
hashTable.Add("2", "BBB");
hashTable.Add("3", "CCC");
IDictionaryEnumerator hashEnum = hashTable.GetEnumerator();
while ( hashEnum.MoveNext())
{
Console.WriteLine(hashEnum.Key.ToString() + ":" + hashEnum.Value.ToString());
}

A simple foreach over the Keys property should do the job
foreach(object obj in hashtable.Keys)
{
...
}

Or even simpler, over the Values, if those are what you're interested in.

Or, even more complete, use
foreach (DictionaryEntry ent in myHashtable)
{
...
}where you immediately get each key-value-pair...

I'm using crystal reports to view data in an access database. The problem I am having is that the report is not releasing the access database.The lock file is still there when I close the Form that the Report is in. I have to close the program and restart to release the database.
I have tried the "Dispose" method when closing the form. That seemed to work for a while but I eventually had to close the program again because the database was not being released.
Are there any suggestions? I would like to close the Report's connection to the database everytime that I close the Report's form.

I am presently trying to use just the UNC patch to the location of the batch.exe file that is located on a server. The example I am attempting is here below.
Process p = null;
p = new Process();
string targetDir;
targetDir = string.Format(@"\\servername\sharename\foldername\parentfolder");
p.StartInfo.WorkingDirectory = targetDir;
p.StartInfo.FileName = "Scan.bat";
p.StartInfo.Arguments = string.Format("Batch File Console");
p.StartInfo.CreateNoWindow = false;
p.Start();
p.WaitForExit();
Form1 f = new Form1();
MessageBox.Show ("Selected script has been Completed");
this.Close();
Is there a way to use a UNC patch without having a drive letter mapped to this share.
Thanks tstang

Hi,
Just from my experience with rolling out patches over a network I have found that there is no way to use UNC paths within a batch file. MS-DOS doesn't handle them nicely... the only way I could get around this was to add another couple of lines to the start of the batch file that mapped the dir to a driver letter:
net use z: \\PATH_TO_HOST\...<br />
cd z:\<br />
EXEC batchfile.bat
Hope that helps.

Has anyone been working with the VS 2005 Beta? I've been trying to deploy to my mobile device but it says I need an updated version of Active Sync. I already have 3.8 - is there a newer Beta version I can use?

Hi,
A programmer who used to work in my position created an application in ASP.net & c# (web application) to print a label in zebra printer Ht-146. I am so new to this kind of application and not sure how he did that. I think he used EPL2 programming language to print it. Right now the printer company zebra has discontinued this printer and I am not sure where to get help from. I don't have their programmer's manual to learn the EPL2language. My question is, is there any way that i could preview the label before printing it. Below is the code to print the label:
public int printlabel(string field1, string field2){
StringBuilder sb = new StringBuilder(2500);
//O-Hardware oprions. O- Disable all the options
sb.Append("O" + Environment.NewLine);
//Q-will cause the printer to recalculate and reformat the image buffer.
sb.Append("Q1014,1" + Environment.NewLine);
//q-set label width.
sb.Append("q608" + Environment.NewLine);
//S-selects the speed of the printer
sb.Append("S3" + Environment.NewLine);
//D-Print density
sb.Append("D5" + Environment.NewLine);
//Z-Print orientation T-Prining from top of image buffer
sb.Append("ZT" + Environment.NewLine);
//JF-Top of the form back up feature
sb.Append("JF" + Environment.NewLine);
sb.Append(Environment.NewLine);
//N-Clears the image buffer prior to building a new label image
sb.Append("N" + Environment.NewLine);
//LE-Line draw exclusive
sb.Append("LE305,2,1,1013" + Environment.NewLine);
//X-Draws a box shape P1-Horizontal start position P2-Vertical start position P3-Line thickness
//P4-Horizontal end position P5-Vertical end position
sb.Append("X305,507,1,458,1016" + Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append("X305,0,1,458,509" + Environment.NewLine);
sb.Append(Environment.NewLine);
//A -Command(ASCII), P1-Horizontal start position P2-Vertical Start Position P3-Rotation (3-270 degrees)
//P4 - Font Selection P5- Horizontal multiplier P6 - Vertical multiplier N-Normal or R-Reverse image.
sb.Append("A10,1009,3,3,1,1,N,\"PART NO. AND ITEM DESCRIPTION\"" + Environment.NewLine);
//LE-Line Draw Exclusive P1-Horizontal start position P2-Vertical start posiion P3-Horizontal length in dots
//P4-P4-Vertical length in dots
sb.Append("LE83,38,1,508" + Environment.NewLine);
sb.Append("LE83,38,1,508" + Environment.NewLine);
sb.Append("A109,1010,3,3,1,1,N,\"PN: " + field1 + "\"" + Environment.NewLine);
sb.Append("A133,1010,3,3,1,1,N,\"\"" + Environment.NewLine);
sb.Append("A157,1010,3,3,1,1,N,\"\"" + Environment.NewLine);
sb.Append("A181,1010,3,3,1,1,N,\"" + field2 + "\"" + Environment.NewLine);
sb.Append("A205,1010,3,3,1,1,N,\"\"" + Environment.NewLine);
printString = sb.ToString();
sendBytes = Encoding.ASCII.GetBytes(printString);
strlength = printString.Length;
try
{
TcpClient printer = new TcpClient(ip,portno);
NetworkStream strm = printer.GetStream();
strm.Write(sendBytes, 0, strlength);
strm.Close();
printer.Close();
}
catch (Exception exc)
{
return -1;
}
return 1;
}
Can anyone explain me whether there is any way to preview this label before printing it?
Is it possible for me to preview the label just by installing the print driver without the printer itself?
I would really appreciate your help.
NOTE: We have Bar-one software to create the label but not sure how to do that.
Thanks

i have one document which describes the PCL of zebra printers, let me know your mail id, so that i can mail that to you.
Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

Hi,
I have 3 questions.
1: How to Get sql numeric datatype in C#.Net
Exp:
dr.GetInt32(); // What will here
2:I have a combox which bind with a default View Manager and i set properties of combox like this:
adpclientinfo.Fill(dsclientinfo);
this.dviewmgrclient = dsclientinfo.DefaultViewManager;
this.cbclientname.DataSource = this.dviewmgrclient;
this.cbclientname.DisplayMember = "Client_Info.Client_Name";
this.cbclientname.ValueMember = "Client_Info.Client_Name";
this.txtclientcode.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.dviewmgrclient, "Client_Info.Client_Id"));
Now i get value from db table and i want to select(mean select index or any other) same value from combox.
I use this.cbclientname.selectedValue = dr.GetString(0); //Client Name

(1) dr.GetInt32(index);
or Convert.Int32(dr.GetValue(index));
index being the index of the column in a particular record.
(2) this.cbclientname.selectedValue = dr.GetString(0); //Client Name
wont work. You will have to assign the actual object from the list.
The workaround is to set the text property.
this.cbclientname.Text = dr.GetString(0);
The combobox will automatically try to find a match from the datasource and if a
match is found SelectedIndex changes automatically.

Thanks for help but i didn't understand the answer of my second question:
==============================================
2) this.cbclientname.selectedValue = dr.GetString(0); //Client Name
wont work. You will have to assign the actual object from the list.
The workaround is to set the text property.
this.cbclientname.Text = dr.GetString(0);
The combobox will automatically try to find a match from the datasource and if a
match is found SelectedIndex changes automatically.
========================================
I get Value from GetString(0) is SK Technology and in combox it exits in second index i want to select SK Technology. which property of combox work.
1: SelectedItem
2: SelectedText
3: SelectedValue

You should just set the Text property.
Setting the SelectedItem to work you must set the value to an actual object(not just text) from the source list.

Hello, I have created a Solution in C#.Net which consists of 3 separate
projects and numerous dependency files which are organized into
directories such as databases, images, usage files, etc. When the
program runs, it searchs for the various files it needs in each of
these directories. I am now working on creating an Installer project
for this Solution so that it may be simply installed on a user's
computer. I have added all of the necessary files to this
Installer/Set-up project and I see that it is possible to specify where
these files are installed onto a new computer but changing the "Folder"
property for each dependency to either "Application Folder", "User's
Desktop", or "User's Programs Menu". I would like to know how I can
specify that a dependency file be installed to a custom location such
as "Application Folder/images/". There must be some simple way to do
this that I am just missing. Any help would be much appreciated.
Thank you.

Is it possible to create any kind of script page that would serve as a tunneling application on a server? ASP/PHP or a .NET Webservice? Then use a windows application to perform the tunneling, etc...just like http-tunnel and hopster.
