Drag&Drop over RichTextBox showing wrong DropEffect

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>();
// in loop
dataSource.Add(new XHolder(reader[0].ToString(), reader[1].ToString())); // Add Constructor

lbServerList.DataSource = dataSource;
lbServerList.DisplayMember = "Name";
lbServerList.ValueMember = "ID";</xholder></xholder>

I wrote code in CP, it may have errors Wink | ;)

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

Designing Menu/tool bar system takes action depending on control displayed

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.

Problem is

for (int i = 0; i <= MainNode.Nodes.Count; i++)
                           {                               MainNode.Nodes.Add(ChildNode);
                           }

why this loop...you should learn about recursive methods Wink | ;)

DataGridView doesn't display anything.

Hello!
I have 2 forms. The first has a DataSet with a table("Table1"), the second form has a BindingSource, BindingNavigator, DataGridView;

<br />
//...<br />
Form1 fmMain=new Form1;<br />
//...Button click<br />
Form2 fmSecond=new Form2();<br />
fm.ShowDialog(fmMain)<br />
//...<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 />
//...<br />
Form1 fmMain=new Form1;<br />
//...Button click<br />
Form2 fmSecond=new Form2();<br />
fm.ShowDialog(fmMain)<br />
//...<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.

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;

Something is wrong in your code with the way you are communicating with the web server is the summary. Or something is wrong with the web server, I assumed it was your code because, well, you didn't understand the article.

MamthaLalith16-Feb-09 2:15

16-Feb-09 2:15

Yes, first thing that really comes up should be there is something wrong with my code.
the intresting thing is it is working fine when am running the method explicitly on a button click
and when i run it as a windows service, its throwing me the 400 error.
so this is what confusing me if there is something really wrong with my code then it should break on first attempt.

Thanks,
Mamtha

byte[] result = webCl.UploadFile("http://" + mgr.GetIniString("Server", "name", "localhost") + "/" + mgr.GetIniString("Server", "path", "localhost") + "/uploadFile.php", "POST", cachePath + "/" + TEMP_NAME);
string sresult = System.Text.Encoding.UTF8.GetString(result, 0, result.Length);
if (sresult == null)
{

else
{
retVal = true;
}
}
catch (Exception ex)
{
log.Error(ex.Message.ToString());
}
finally {
File.Delete(cachePath + "/" + TEMP_NAME);
}

its actually throwing the 400 bad request at webcl.iploadfile method
