I am working on a FTP client that works great but when I use file drop from windows explorer the application crashes and ends. The error breaks at the Application.Run(new Mainform); and gives me the following error: "An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in system.windows.forms.dll
Additional information: External component has thrown an exception." If I put a try catch around that I get this error message Exception.Message = "External component has thrown an exception."
I am using Visual Themes and are sure that that is the problem.
<br />
[STAThread]<br />
static void Main() <br />
{<br />
try<br />
{<br />
Application.EnableVisualStyles();<br />
Application.DoEvents();<br />
Application.Run(new MainForm());<br />
}<br />
catch(Exception Ex)<br />
{<br />
MessageBox.Show(Ex.Message,"Runtime Error.",MessageBoxButtons.OK,MessageBoxIcon.Error);<br />
}<br />
}<br />
When I take the EnableVisualStyles(); out it works fine. Also when I do a file drop, my progressbar losses the Visual Theme.
How do I get around this and still use the Visual Themes?
Here is my Drop code:
<br />
private void listView1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)<br />
{<br />
if( e.Data.GetDataPresent(DataFormats.FileDrop, false))<br />
{<br />
string[] files_str = (string[])e.Data.GetData(DataFormats.FileDrop);<br />
<br />
foreach(string file_str in files_str)<br />
{<br />
FileInfo droppedFile = new FileInfo(file_str);<br />
<br />
if(droppedFile.Exists)<br />
{<br />
UploadFile(droppedFile);<br />
}<br />
else if(droppedFile.Directory.Exists)<br />
{<br />
DirectoryInfo droppedDirectory = new DirectoryInfo(file_str);<br />
<br />
if(droppedDirectory.Exists)<br />
{<br />
UploadDirectoryChanges(droppedFile.Directory);<br />
}<br />
}<br />
else<br />
{<br />
MessageBox.Show(file_str +"\nis not recognized as a valid file drop.","Unsupported File drop!",MessageBoxButtons.OK, MessageBoxIcon.Information);<br />
}<br />
}<br />
}<br />
}<br />

Your linked article deals with the Data Access Application Block. The OP never mentioned anything about that.

Yes:
SqlParameter[] parameters = new SqlParameter[numParameters];
parameters[0] = new SqlParameter.....

Loop round the array adding each parameter. See the example on MSDN: SqlCommand.Parameters Property[^]

I am trying to determine the feasability of converting the SAC Java classes for CSS parsing from from Java to C#. I thought I had read somewhere that you could convert the Java classes to J# then convert them to C#. Also, I thought I had seen a Java converter program from Mircosoft.
Anyone have any suggestions if this is possible and maybe the best approach to take?
|
|

|

I've never tried J# before. But if you can use your code in J#, then you can also use your code in C#. Just compile your code using J# into DLL and use this DLL from C#.

And try the demo software and you can convert the code,

Search "Reading a text file in C#" in google.
Once you have a line of text from the file you can use string.Spilt(','); to seperate the info. Something like:
string currentText;
string [] seperated = currentText.Split(',');

I have dropdown list with over 50 list item. Based on each selection i want to call a function which populate the DataGrid.
Currently, I am doing it following way .. but calling switch case 50 times sounds tidius .. there has to be a better way... seems like it's very common .. for example ... select a State from the dropDownlist and instead of DataGrid they are populating another drpodownlist which is cities in that state.
protected void DropDownList1_SelectedIndexChanged1(object sender, EventArgs e)
{
string tableName = DropDownList1.SelectedItem.Text;
switch (tableName)
{
case "Address":
GetAllAddressData();
break;
case "State":
GetAllAddressData();
break;
.......................
Any ideas or suggestions are really appriciated ...
Thanks

As far as i am aware, the standard way of doing it would be have your query / SP text that u will be using to populate your data. On select, read the key out of the selected item, and insert it into your query string, and execute.
i.e.
<br />
protected void DropDownList1_SelectedIndexChanged1(object sender, EventArgs e)<br />
{<br />
const int DEFAULT = 0;<br />
const string SQL = "EXEC GetStateListByID {1}"<br />
<br />
int liIndex;<br />
string lstrSQL;<br />
<br />
liIndex = (int)DropDownList1.SelectedItem.Value;<br />
<br />
if(liIndex == DEFALT)<br />
return;<br />
<br />
lstrSQL = string.Format(SQL, liIndex)<br />
<br />
<br />
this.PopulateDataGrid(lstrSQL);<br />
<br />
}<br />
<br />
That's the simple version anyway. Hope it helps.

Hi All,
I have two multiline textboxes one above the other that both have horizontal scroll bars.
How would I make it so that when one scroll bar is moved, the other textbox's scroll bar is also automatically adjusted so that they always line up?
Thanks

Hi
I've the following line:
MethodInfoArray[i].Invoke(new object(),datafrominputs);
where datafrominputs is an object[] containing 2 or more items. I defined the method it is invoking like this:
static public int function(params int[] numbers)
Am I correct in assuming this will allow any number of inputs? why do I get a TargetParameterCountException?
cheers
|
|
|
|
|
datafrominputs needs to be object[][] of size 1 and the original object[] should be the first element. iow:
MethodInfoArray[i].Invoke(new object(), new object[] { datafrominputs });

I have to parse some XML files (more than 5.000 files). All of them are compressed with gzip, and so does the DTD of each one.
Using GZipStream, I can read the XML (i'm using XPathDocument), but it generates an exception "Expected DTD markup was not found", because the DTD also is gzipped.
I did a test, replacing the DTD of one XML with a normal file (not compressed), and it worked.
Is there any way to parse these XML files without having to extract the DTD, decompress them and modify the DTD reference in the XML files?
Thanks in advance!
