Hi,
I need to create ASP.net application which can convert Office 2007 Word document(*.docx) file to PDF document. Application has constraint as below,
1. Office 2007 is not installed on web server. (Server which is going to host ASP.net application.)
2. Web server will have Window 2003 installed.
3. Web server has Framework 2.0 installed.
Can anyone suggest me how to convert document into PDF with describe limitation.
I appreciate if anyone suggest third party DLL(Paid or Free) which can do that.
Thanks,
Mayur Patel

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
the code is:
SqlConnection cn = new SqlConnection(@"Data Source='MOHAMEDEWEHISHY\SQLEXPRESS';Initial Catalog='Computer Sales System';integrated security=sspi");
try
{
SqlCommand cmd = new SqlCommand("backup_database", cn);
cmd.CommandType = CommandType.StoredProcedure;
if (System.IO.File.Exists(@"D:\SQLServerBackups\Computer Sales System.bak"))
{
System.IO.File.Delete(@"D:\SQLServerBackups\Computer Sales System.bak");
}
cn.Open();
int i = cmd.ExecuteNonQuery();
if (i < 0)
{
MessageBox.Show("Your database is backed up successfully");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
MessageBox.Show("Sorry ... You can not back up your database");
}
finally
{
cn.Close();
}
so the problem is using SqlConnection with others not DML commands
i tried to use OLEDBConnection but it not gets result
So what is the solution????????
Thanks,

i have a datatable and i have to show the data of its 3rd column in gridview.hw can i do that
|
|
|
|

By binding it to the gridview. Plenty of examples are there on web. You can read through them.

Hi,
I am using a text box on the UI to query the database using the entered text.
Following is the code snippet
string refNum = (from Example in db.Orders
where Example.Reference == textBox1.Text
select Example.OrderId).First().ToString();
My question is..
How to show a friendly error message if Example.Reference is not equal to input value in textBox OR if no value is entered into the text field ?
Because am getting this error "{"Sequence contains no elements"}" when no value is entered or if any wrong value is eneterd. Can any1 tell me how to catch this error and show it as a friendly message to the user.
Thanks,
|

if (string.IsNullOrEmpty(textBox1.Text)) {
MessageBox.Show("Please enter some data.");
} else {
your code...
}

Thanks ,

Use FirstOrDefault instead of First.

Thanks mate

if (string.IsNullOrEmpty(textBox1.Text)) {
MessageBox.Show("Please enter some data.");
} else if (!IsValidInput(textBox1.Text)) {
MessageBox.Show("Not a valid input.");
} else {
your code...
}
Write a method IsValidInput that queries the database to find out if the input is valid and returns true or false accordingly.

Hi
I add a panel to my form in code behind.
how can i set background of panel in code behind?
how can i add this panel to my form in code behind?
THX alot

Try doing it in the designer and then looking at the code the designer generates.
However, remember to set the size and location as well. E.g. :
Panel mypanel = new Panel();
mypanel.BackColor = System.Drawing.Color.Red;
mypanel.Size = new System.Drawing.Size(100,200);
mypanel.Location = new System.Drawing.Point(10,10);
this.Controls.Add(myPanel);
If you have knowledge, let others light their candles at it.

Hi everyone...
I'm using an SQL Server Compact Edition
I can do all the queries without a problem but I cannot create a table.
in the runtime, when it comes to create a table, the line of the "ExecutNonQuery" gives an error:
"There was an error parsing the query [Token line number=1, Token line offset = 14]..etc"
I now that this kind of error appears when your SQL command syntax is wrong
can anybody tell me what is my fault?
string CreCom = "CREATE TABLE " + TCkim + YilBox.Text + " (Aylar nvarchar (10), Statu nvarchar (20), Odeme nvarchar (20), Servis nvarchar (20), Kiyafet nvarchar (20), Kitap nvarchar (20), Tiyatro nvarchar (20), Sinema nvarchar (20), Yemek nvarchar (20), Muze nvarchar (20), Piknik nvarchar (20), Parti nvarchar (20), Diger nvarchar (20), Yoklama nvarchar (20), Aylik nvarchar (20), Odenen nvarchar (20), Kalan nvarchar (20))";
SqlCeCommand CreateCommand = new SqlCeCommand(CreCom, conn);
CreateCommand.ExecuteNonQuery();
note: SqlCeCommand is the "SqlCommand" for Compact Edition. Usage is all the same
|
|
|
|
|
BTW
my CreCom string is created as below in the runtime:
"CREATE TABLE 444442009 (Aylar nvarchar (10), Statu nvarchar (20), Odeme nvarchar (20), Servis nvarchar (20), Kiyafet nvarchar (20), Kitap nvarchar (20), Tiyatro nvarchar (20), Sinema nvarchar (20), Yemek nvarchar (20), Muze nvarchar (20), Piknik nvarchar (20), Parti nvarchar (20), Diger nvarchar (20), Yoklama nvarchar (20), Aylik nvarchar (20), Odenen nvarchar (20), Kalan nvarchar (20))"
is there something wrong?

well,
I just found out that when I put an "a" to the beginning of the table name, this problem is no more
but still, thank you all =)

|

a table name is an identifier, it cannot start with a digit. Similar to most programming languages.

table A
Field: a(char(40)) b(char(40))
q -- ss
q -- fs
q -- ffr
q -- egg
w -- ffh
w -- gykk
e -- hrh
e -- kyk
e -- jjtj
the Purpose: field "a" as father node,field "b" as child node,field "a" should not be repeated!this is part of my code,but it can't meet my Requirements.
public void AddTree(TreeNode pNode)
{
DataSet ds=new DataSet();
DataView dvTree = new DataView(ds.Tables[0]);
foreach (DataRowView Row in dvTree)
{
if (pNode == null)
{ //add father node
TreeNode Node = treeView1.Nodes.Add(Row["a"].ToString());
}
else
{
TreeNode Node = pNode.Nodes.Add(Row["b"].ToString());
}
}
it only can show feild "a" on treeview,like this:
q
q
q
q
w
w
e
e
e it repeat the Field 'a',can someone help me ,thanks very much!!   always waiting online

Looking at the sample you've posted, pNode will always be null, hence the reason a is shown again and again. What you need to do is:
if (pNode == null)
{
pNode = treeView1.Nodes.Add(Row["a"].ToString());
}
else
{
TreeNode Node = pNode.Nodes.Add(Row["b"].ToString());
}

i want get the Results like
q(father node)
..ff(child node)
..grt
..trt
..hth
w
..trt
..fgh
..hth
e
..htj
..htr
..trt
..ht
which is your changed code shown:
q(father node)
..ff(child node)
..grt
..trt
..hth
..trt
..fgh
..hth
..htj
..htr
..trt
..ht
if do thisif (pNode == null){ //add father node pNode = treeView1.Nodes.Add(Row["a"].ToString());}else{ TreeNode Node = pNode.Nodes.Add(Row["b"].ToString());} pNode=null;
shown only father node like:
q
w
e

To be honest, your logic has more fundamental problems. You have two columns here which you are trying to work with, but the logic you have in the if/else only applies to one column level. What you could do is reimplement your logic like this:
foreach (DataRow dr in ds.Tables[0])
{
string colName = dr["a"].ToString();
TreeNode node = treeView1.Find(colName);
if (node == null)
{
node = treeView1.Nodes.Add(colName, colName);
}
node.Nodes.Add(dr["b"].ToString());
}What you are doing here is adding a node with a specific key into the treeview - and this key is the value of column a. You look for this node using the Find method and add it in if it doesn't exist. Finally, you add column b to the node.
