Darn! Still no good. It makes no sense to me. Why fine on one but not on others?
I used to say that I liked programming because of the instant gratification when you compile an app and it works, but this is an example of the dark counterpoint to that. Instant frustration.

HDR=Yes; Indicates that there are header rows in the sheet,
and IMEX=1; 0 Export mode, 1 Import mode, 2 Linked mode,
I run Imports from excel in 98/XP/Vista with that connection and its all good.
How are you defining your path ie:Filename??
|
|
|
|

This is all the relevant code. I just don't get why it would work for the one system but not the others.
string filename = "C:\\Program files\\Daily_Totals_By_Employee.xls";
string listname = "Sheet1";
OleDbConnection con = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filename + ";Extended Properties = 'Excel 8.0'");
con.Open();
try
{
DataSet myDataSet = new DataSet();
OleDbDataAdapter myCommand = new OleDbDataAdapter(" SELECT * FROM [" + listname + "$]", con);
myCommand.Fill(myDataSet);
con.Close();
|
|
|
|
|
I would try to put the file in a location like "C:\\Myfolder" just to test
eliminate the "Program files" directory and see what happens, also punch in the path manually
Data Source= C:\Myfolder\Daily_Totals_By_Employee.xls
See if any of those work...sorry I can't be any more specific...
|
|
|
|
|
I just tried the path suggestion. I changed the path to
"C:\\csharpdata\\Daily_Totals_By_Employee.xls".
No change.
At the risk of being obtuse, I don't understand how permissions could be the problem. I'm not saying you're all wrong, just that I don't understand it. The file is being opened: wouldn't a permissions issue prevent that? The program opens the file then fails to find the sheet.

Hi all
I'm a dev newbie and am struggling to get my listbox to work they way i want it to. Basically, i want to be able to store the results of my stored procedure within a listbox control - so for example, if my sproc returns ServerID (primarykey) and ServerName (text column), i want this bound to my listbox control.
In my app i have created a datareader which contains the results of my query. As i loop through the datareader, i want to bind my ServerID and ServerName values to the listbox.
At the moment, I can get ServerName to display in my listbox by implementing the following:
listbox.items.add(System.Convert.ToString(reader[1]));
I then assume i need the following code to assign my query results to the displaymember and valuemember properties:
lbServerList.DisplayMember = reader[1].ToString();
lbServerList.ValueMember = reader[0].ToString();
Now i want to be able to select a server from my drop down list, and get the associated serverid. So for testing purposes, i've created a button and when i click the button, i want the serverid corresponding to the selected servername in my listbox, to be written to a textbox:
if (lbServerList.ValueMember != null)
{
textBox.Text = listbox.ValueMember;
}
A number is indeed written to the textbox but it is a random number which doesn't link to the selected servername, and the number doesn't change no matter what server i select.
Can someone please help fill the gaps in my understanding???
I need to know first whether i'm populating the listbox correctly, and then secondly how to retrieve my serverid from it.
Thanks!

divinyl wrote: lbServerList.DisplayMember = reader[1].ToString();lbServerList.ValueMember = reader[0].ToString();
its not like this...
first of all make a class that will hold your data(server name and id thing) with the properties
class XHolder
{
string name;
string id;
public string Name
{ get{ return name;} set { name = value; } }
public string ID
{ get{ return id;} set { id = value; } }
}
now you can use Generic list and add like this
List<xholder> dataSource = new List<xholder>();
dataSource.Add(new XHolder(reader[0].ToString(), reader[1].ToString()));
lbServerList.DataSource = dataSource;
lbServerList.DisplayMember = "Name";
lbServerList.ValueMember = "ID";</xholder></xholder>
I wrote code in CP, it may have errors

Hi guys!
I'm struggling with a weird problem I'm unable to solve so far.
I want to enable drag&drop of mail attachments from Outlook.
This does work when my drop target is, for example, a Form or a Panel; I can get all the file names and contents, no problem.
As soon as I try the same with a RichTextBox as drop target, it doesn't work - whatever I set the desired DropEffect to (usually DropEffect.Copy), the cursor is always DropEffect.Move when dragging files from Explorer over the RTB (minor nuisance) and DropEffect.None if I drag mail attachments from Outlook (showstopper).
It doesn't matter if I set the effect in DragEnter or DragOver, if EnableAutoDragDrop is true or false, I've even tried loading a Rich Edit control 4.1 instead of the default V2.0, but to no avail.
Can anyone help?
Thanks in advance!
Regards,
mav

Thanks, but what exactly do you mean by "windows inbuilt text effects"?
It's not that I don't know how to handle drag&drop from outlook in general (it's working fine on non-RichTextBox controls as drop targets). The question is how to make the RTB appreciate the DragDropEffect I set in the DragEnter/DragOver events and not to tell the user that he can't drop an attachment there when I explicitely set the DragDropEffect to Copy.

mav

I’m a new developer in a very complex project. I like to create a program that can plot the methods that is executing in the program to get a fast view of what is calling what. Of course I can debug the program but the best way right now is to write some code like this:
StackTrace s = new StackTrace();
CallAMettodThatDoesALotOfOtherCalls();
s.PrintAllCalledMethodsInAnEasyToReadWay();
Any tip on code/tool that manages that?

Hi,
I have a webform that shows summary information at the top of the page.
If there is only one "row" in the database for the associated project, the summary looks like this:
Tool_ID= "returned value"
Tool ="returned value"
Tool_Quantity= "returned value"
However if there are multiple tool_ids associated with the project in session (ex, 2 tools), the summary will display each tool in its own column:
Tool_ID= "returned value" Tool_ID= "returned value"
Tool ="returned value" Tool ="returned value"
Tool_Quantity= "returned value" Tool_Quantity= "returned value"
The maximum number of Tool_ids that can be associated with any project is 3. I have a query that will search the project and get the tool_ids, tool and tool_quantity, but I dont know how to code in to display the output as I have listed above. I also need this to be able to get updated as the user can add more tools to the project before submission. Please help!
Thank you

I have created an application and I am using a panel to load and display custom user controls.
In all these custom controls, there is need save data or cancel changes. I want to design a menu or a tool bar with the save and cancel commands such that changes are saved or cancel depending on the control currently displayed. The save changes command is a little complex for me because the code for saving data would be different for each control. How can I design my menu/tool bar such that the right code executes depending on the displayed control?
Secondly, in my display panel how can I get a "reference" ton the currently displayed/visible control. There could be other controls in the back ground hidden by the current control but I just to be able to reference only the top-most control. NB When I load a control, set I it to fill up the entire panel space which hides any control that may have been visible before but I suppose that does not necessarilly set the visible flag of the previous control to false so. So I can't use the Visible property to check for the "visible" control.
Thanks for you help.

I have tried the following code..but I am able to fill only one product under one sub category. Please help me out how to??initialize and fill the data into tree view
foreach (DataRow row in table.Rows)
{

Problem is
for (int i = 0; i <= MainNode.Nodes.Count; i++)
{ MainNode.Nodes.Add(ChildNode);
}
why this loop...you should learn about recursive methods

Hello!
I have 2 forms. The first has a DataSet with a table("Table1"), the second form has a BindingSource, BindingNavigator, DataGridView;
<br />
Form1 fmMain=new Form1;<br />
Form2 fmSecond=new Form2();<br />
fm.ShowDialog(fmMain)<br />
private void Form2_Load(object sender, EventArgs e)<br />
{<br />
BindingSource.DataSource = ((Form1)this.Parent).DataSet;<br />
BindingSource.DataMember = "Table";<br />
DataGridView.DataSource=BindingSource;<br />
BindingNavigator.BindingSource=BindingSource;<br />
}<br />
BindingNavigator shows that there are 100 rows and the position=1, but DataGridView doesn't display anything.
But this code works:
<br />
Form1 fmMain=new Form1;<br />
Form2 fmSecond=new Form2();<br />
fm.ShowDialog(fmMain)<br />
private void Form2_Load(object sender, EventArgs e)<br />
{<br />
DataGridView dt = new DataGridView();<br />
BindingSource.DataSource = ((Form1)this.Parent).DataSet;<br />
BindingSource.DataMember = "Table";<br />
dt.DataSource=BindingSource;<br />
dt.Parent = this;<br />
BindingNavigator.BindingSource=BindingSource;<br />
}<br />
Does anybody have some ideeas?

at least can you see the column headers? Do you use AutoGenerateColumns = true, or defined columns?

I cannot see them, the DataGridView is empty.
Calin Tatar
Where have you found the property "AutoGenerateColumns"?, I couldn't find it.
|
|
|
|
|
AutoGenerateColumns is not browseable in propertygrid.
You may use it from code:
dataGridView.AutoGenerateColumns = true;
