I was just having this problem with one of my programs. What I had to do was create a single scrollviewer and then I had to embed a wrappanel or stackpanel inside of it. Then make sure the scrollviewer CanContentScroll property is set to false.

I build an application in C# with crystal reports. If I try to use application in user's machine, when I open some crystal rep. I get this messagebox:
Cannot find keycodeV2.dll or invalid keycode.
Can somebody tell me what's the problem

Search Google. Crystal is notorious for this. Also, you can only redistribute binaries and not source with Crystal unless everyone has a license.

I have written a window service in C#. On windows XP it runs fine. I checked it on my computer and some other computers in office. I am able to install it on production system. But when i try to run this service i receive following error:
"ERROR 1053: The service did not respond to the start or control request in timely fashion"
I google on this error. Most of people are saying that Start method of service should return as soon as possible. In my start method, i am opening a file, making a socket and creating and starting a thread.
After this when i try to uninstall the service i got following error:
Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'file:///C:\game firewall\New Folder (4)\Firewall.exe' or one of its dependencies. The module was expected to contain an assembly manifest..
ANY BODY COULD TELL ME TO RESOLVE THAT PROBLEM?

Well, is that file there in the first place? Also, why on earth would you want to name an application folder New Folder (4) ?
If the file *is* there and you *want* that folder name, check the folder permissions. Then try opening it using ildasm.

I have to copy again to uninstall the windows service. That is why "New Folder (4)" i am copying fourth time to uninstall the application and then trying to reinstall.
I have given all permission to administrator as well as creator. By using ildasm i compare uploaded exe file and local exe file. Both have same manifest also same structure of classes.
ANY OTHER HELP?

I have a ComboBox that is populated with values from a MS Access table. Next I use the below code to delete the record that is selected in the comboBox.
private void button3_Click(object sender, EventArgs e)
{
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\Magazi.mdb");
conn.Open();
OleDbCommand cmd = new OleDbCommand("DELETE FROM Suppliers WHERE Name=@Name", conn);
OleDbParameter parDel = new OleDbParameter();
parDel.ParameterName = "@Name";
parDel.Value = comboBox1.SelectedItem;
cmd.Parameters.Add(parDel);
cmd.ExecuteNonQuery();
conn.Close();
}
For some reason I get an "OleDbException was unhandled" message...
|
|
|
|
|
Plz. use "comboBox1.SelectedValue" rather than comboBox1.SelectedItem;.
|
|
|
|
|
SelectedItem.ToString(); might solve your problem. If you're adding objects rather than strings so your comboBox make sure you've overridden the ToString method.

Ok. I have tried some things and this what I get...
Using the below code and I have also display member, value member and SelectedValue of the comBox set to Name.
private void button3_Click(object sender, EventArgs e)
{
OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\Magazi.mdb");
conn.Open();
OleDbCommand cmd = new OleDbCommand("DELETE FROM Suppliers WHERE Name=@Name", conn);
OleDbParameter parDel = new OleDbParameter();
parDel.ParameterName = "@Name";
parDel.Value = comboBox1.SelectedValue.ToString();
cmd.Parameters.Add(parDel);
cmd.ExecuteNonQuery();
conn.Close();
}
When I try to select a value from comboBox I get this message:
Column 'Name' is constrained to be unique. Value 'Champion' is already present.

|
|
|
Use this
comboBox1.SelectedItem.ToString();
|
|
|

Hi Guy
I seen your code in above. i seen may be ur combobox haven't a selected value may be pass null value, so error will raise.
and second may be comboBox haven't records. so verify both condition after get comboBox1.SelectedItem.
when directly to use comboBox value we must do validations.that's give error free to us.
thanks

Hi Guroos,
I want to send newsletter to all recipients. I do not want to write all email address in BCC. and Also do not want to write in TO box. What should I do?
Simply I want every member should get newsletter with his own email address in TO box.

AkmalSyed,
You could do it in a loop.
foreach (string email in emailCollection)
{
string header = "welcome to spammers are us!";
string body = "your message";
Email email = new Email();
email.Header = header;
email.Body = body;
email.EmailAddress = email;
email.Send();
}

It's rude to ask people to do your work for you. The poster gave you some useful advice. I suggest you use it to solve the problem yourself.

If you mean a web page, you can use Img[^] tag
If you are trying to use display it in a form, use PictureBox[^] control

Just use the relative path for fileToDisplay. Example: "cool.bmp" or "..\\images\\cool.bmp".

RajeevKumarSharma,
You have to ways. Use Graphics to do it, or use a PictureBox. I am guessing your pretty new to C# so id go with PictureBox.
Regards,
Gareth.

This should do what you want
Bitmap pic = new Bitmap(fname);
xsize = pic.Width;
ysize = pic.Height;
// Adjust the position of the picture box
pictureBox1.Location = new System.Drawing.Point((0, 0);
// Adjust the size of the picture box
pictureBox1.Size = new System.Drawing.Size(xsize, ysize);
// Display the image
pictureBox1.Image = pic;

I have a dropdownlist that contains items ,
each item points to the each tablename of a fixed database.
I simply added a blank CrystalReport1 without adding any table, any logon informatio while creating Crystal Report.
and also added CrystalReportViewer Control.
private void Page_Load(object sender, System.EventArgs e)
{
if(dropdownlist1.Selectedvalue=="Table1")
{
SqlConnection con=new SqlConnection();
con.ConnectionString="Server=.;uid=sa;pwd=abc;database=db";
con.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from table1",con);
DataSet ds=new DataSet();
da.Fill(ds);
//ds.Tables.Add();
CrystalReport1 report2=new CrystalReport1();
//report2.SetDatabaseLogon("userid","pwd");
report2.SetDataSource(ds);
//CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.ReportSource =report2;
CrystalReportViewer1.RefreshReport();
}
else if(dropdownlist1.Selectedvalue=="Table2")
{
SqlConnection con=new SqlConnection();
con.ConnectionString="Server=.;uid=sa;pwd=abc;database=db";
con.Open();
SqlDataAdapter da = new SqlDataAdapter("select * from table2",con);
DataSet ds=new DataSet();
da.Fill(ds);
//ds.Tables.Add();
CrystalReport1 report2=new CrystalReport1();
//report2.SetDatabaseLogon("userid","pwd");
report2.SetDataSource(ds);
//CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.ReportSource =report2;
CrystalReportViewer1.RefreshReport();
}
}
and so on.........
=====================================================
crystal Reprt is coming without data and columns of the table,(Ensuring the table contains data),i think the dataset is not attached ,
