Resizing DateTimePicker to fit max value text - C# Discussion Boards

Hello.

I have this wierd problem when im writing to a text file with data from a array

I have this method:

private void writeData()
{
    // Open file
    StreamWriter writeData = new StreamWriter(saveMonsterSetBase.FileName, false);

    // Write all data from array to file
    for (int x = 0; x < MonsterSetBaseDataArray.Count; x++)
    {
        writeData.WriteLine(MonsterSetBaseDataArray[x]);
    }

    // Close stream
    writeData.Close();
}

Which is trigged here:

saveMonsterSetBase.ShowDialog();

if (saveMonsterSetBase.FileName != "")
{
    writeData();
}

It works fine and opens my saveFileDialog

But after I save it I get a "file not found" on some other method I use

This is some of the method:

// Opening txt file with location from XML
StreamReader findMonsterStream = new StreamReader(@XMLmonsterLocation);

I get the error monster.txt (XMLmonsterLocation) is not found

It looks like the writedata changes the local path because it says

File not found in the path where I saved the file

Example:
The application and monster.txt (XMLmonsterLocation) is saved in D:\

I then use the saveFileDialog (I save a file to for example C:\) and when I access my method where I use the XMLmonsterLocation it says file not found in C:\

So I dont know why

Hope you understand

The StreamReader reads from a xml file that looks like this:

<config>
<monsterlocation>monster.txt</monsterlocation>
<monstersetbaselocation>MonsterSetBase.txt</monstersetbaselocation>
<monsterimagelocation>mobs\</monsterimagelocation>
<mapimagelocation>maps\</mapimagelocation>
<mapinfolocation>maps\maps.txt</mapinfolocation>
</config>

Hi,

Windows keeps a "current directory" for every process.
There are several ways to modify the curdir, browsing with an Open/SaveFileDialog is one of them;
check this: the second time you open such a dialog, it shows the folder you saw last.

You can prevent this from persisting by setting FileDialog.RestoreDirectory true.

In general you should not rely on the curdir, so basically your mistake is that the
StreamReader uses a relative path. If you want it to always read files from your EXE's folder
write code to enforce that; have a look at Application.StartUpPath

Deserialize an object and write it to a file

Purpose : Read the contents of a CSV file and write it to a database in a varbinary field. Once written, read the contents and write it to a CSV file.

Issue: I am able to serialize and write the contents to the database.I am having issues when I deserilaize the file contents. I am getting an error "Trying to deserilaize an empty stream".

Please find below the code used to serialize and deserialize

private object SerializeFileContent(string filePath)
{
if (filePath != null)
{
//write the fielcontents to a byte array
FileStream st = new FileStream(filePath, FileMode.Open);
byte[] buffer = new byte[st.Length];
st.Read(buffer, 0, (int)st.Length);
st.Close();

//serilaize the bytearray and write it to a memory stream
MemoryStream serializedStream = new MemoryStream();
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(serializedStream,buffer);

//Read Memory Stream into Byte Array
int streamLength = Convert.ToInt32(serializedStream.Length);
byte[] serilaizedArray = new byte[streamLength];
serializedStream.Write(serilaizedArray,0,streamLength);

return serilaizedArray;

}
else
return null;

} public void DeserializeFileContent(string FileId,string filePath)
{

//read the file contents and write it to a stream
SqlConnection CCSProductCatalogArchiveConn = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["CatalogArchiveConnectionString"]);
SqlParameter sqlFileId = new SqlParameter("@FileId", SqlDbType.NVarChar,100);
sqlFileId .Value = FileId;

//Populates parameter array to be passed into DataUtil.ExecuteNonQuery
SqlParameter[] sqlParams = new SqlParameter[1];
sqlParams[0] = sqlFileId;

DataSet fileContents = DataUtil.LoadDataSet(CCSProductCatalogArchiveConn, "GetFileContents", true, sqlParams);

MemoryStream mstream = new MemoryStream();
StreamWriter writer = new StreamWriter((mstream);
writer.Write(fileContents);

mstream.Length
//Deserialize the contents
object o;
BinaryFormatter formatter = new BinaryFormatter();
o = (object) formatter.Deserialize(mstream);
}
Thanks

You need to reset the position to 0 after that Smile | :)

Resizing DateTimePicker to fit max value text

I am creating a ToolStrip that I have a DateTimePicker added on using the following code:

DateTimePicker FromDate = new DateTimePicker();

FromDate.Format = DateTimePickerFormat.Short;

MainToolStrip.Items.Add(new ToolStripControlHost(FromDate));

I am wanting to change the width of the DateTimePicker to be just large enough to fit the text needed. My thought was to measure the MaxDate value string using the font and that would be the width, like so:

Size dtps = TextRenderer.MeasureText(FromDate.MaxDate.ToShortDateString(), FromDate.Font);

FromDate.Size = dtps;

This works, except for one problem, it does not include the width for the drop down button on the DateTimePicker control, so it overlaps the text. I do not know how to get the width of the drop down button on the DateTimePicker, and my searches have been less than successful. Does anyone have a reference to where I can learn how to do this?

Also, is there any good references that go into some of this type of detail? Most of the books and websites I visit will teach you the basics of a control, like how to change the font, width, height, and common properties, but I would like to get a bit deeper with these items and really see what they can do. I think these books might be what I am looking for, but have not got them yet:
'GDI+ Custom Controls with Visual C# 2005' by Tiberiu Radu, Iulian Serban, Dragos Brezoi, Adam Ward
'Pro .NET 2.0 Windows Forms and Custom Controls in C#' by Matthew MacDonald
'Windows Forms 2.0 Programming' by Chris Sells, Michael Weinhardt

Anyone have any experience with these books, or maybe could recommend something similar?

Thanks for your time, in advance! =)

In regards to measuring your text, you could just add a constant value to the total width assuming the size of the button does not change.

Just because we can; does not mean we should.

I am creating an IE toolbar and I need it to launch a javascript page when the toolbar button is clicked.

Below is the code that I am using and getting errors.

private void btnToolStrip_Click(object sender, EventArgs e)
{

// Launches the post window
Page.ClientScript.RegisterStartupScript(this.GetType(), "CustomButton", "<script language=JavaScript> window.open('http://hvkclncswsvr10.gign.kcl.mtec.mds.lmco.com/tachyon_proj/post/?item='" + content.document.location.href + "'&title='" + encodeURIComponent(document.title) + "','Tachyon Post','width=850,height=500,resizable=yes');</script>");

}

When i build this i get errors on the name Page, content, encodeURIComponent, and document. Is it possible to run the JS this way from a ToolStripButton clcik event or do I need to do it another way?

FileSystemWatcher filter problem and how it works

FSW dont raise event when i set its filter to custom extension, like if i set it to "*.abcd" then no event will raise but if i set it to other known extensions like "*.txt" or something else it works, any idea how to solve ?

my second question is that how it works, is it works like timer mean it keep refresh after some inbuilt specified time or any window function send info to it when a file created and it raises event ?

thanks

FSW monitors a directory for file creation, modification, deletion and renaming. The custom expression is to monitor only those file types that match that expression.

This example monitors only the directory where dir == the directory to monitor and only raise an event on file types of txt.

fileWatcher = new FileSystemWatcher(dir, "*.txt");
fileWatcher.EnableRaisingEvents = false;
fileWatcher.IncludeSubdirectories = false;
fileWatcher.NotifyFilter = NotifyFilters.FileName;
fileWatcher.Created += new FileSystemEventHandler(fileWatcher_Created);

Set fileWatcher.EnableRaisingEvents = true to enable the monitoring. To stop monitoring set the value to false.

FSW.Filter = **.txt"; // will work, if i create any file with extension txt

Not sure where your having problems. I did this test and had no problems getting the notifications.
Sorry

private void Form1_Load(object sender, EventArgs e)
{
    fileSystemWatcher1 = new System.IO.FileSystemWatcher(@"C:\");
    fileSystemWatcher1.IncludeSubdirectories = false;
    fileSystemWatcher1.NotifyFilter = NotifyFilters.FileName;
    fileSystemWatcher1.Filter = "*.abcd";
    fileSystemWatcher1.Created += new System.IO.FileSystemEventHandler(fileSystemWatcher1_Created);
    fileSystemWatcher1.Changed += new System.IO.FileSystemEventHandler(fileSystemWatcher1_Changed);
    fileSystemWatcher1.Renamed += new RenamedEventHandler(fileSystemWatcher1_Renamed);
    fileSystemWatcher1.Deleted += new FileSystemEventHandler(fileSystemWatcher1_Deleted);
    fileSystemWatcher1.EnableRaisingEvents = true;

    File.Delete(@"C:\test.abcd");
    StreamWriter sw = new StreamWriter(@"C:\test.abcd",true);
    sw.WriteLine("test");
    sw.Close();
    sw.Dispose();
}

void fileSystemWatcher1_Deleted(object sender, FileSystemEventArgs e)
{
    MessageBox.Show("File Deleted " + e.FullPath.ToString());
}

void fileSystemWatcher1_Renamed(object sender, RenamedEventArgs e)
{
    MessageBox.Show("File Renamed " + e.FullPath.ToString());
}

void fileSystemWatcher1_Changed(object sender, System.IO.FileSystemEventArgs e)
{
    MessageBox.Show("File Changed " + e.FullPath.ToString());
}

void fileSystemWatcher1_Created(object sender, System.IO.FileSystemEventArgs e)
{
    MessageBox.Show("File Created " + e.FullPath.ToString());
}

What I do is send a (report) file which has a particular extension.

When the user installs my software it registers that extension with one of the programs.
So when the user (who has already installed my software) clicks on the attachment, Windows runs the appropriate program to open the file to display its contents.

Maybe something like that would be better?

how to implement keyboard hotkeys to minimize an application & reopen it?

WebMaster2-Jul-08 3:07

hi everyone,

I have developed an application in C# which runs as system starts up. I also have a system tray icon in task bar. I just want to minimize my application by pressing a keyboard key, say Esc button. &then reload it when i press another button, say F11. I have worked on registry files & set some subkeys &values for it, for example i've set a value for keyboardActivation; the hexadecimal value of F11(which is 570000) & it still doesn't work. I think I know why it doesn't work, 'cause it needs first to be minimized in tray then get reloaded on page, yet I don't know how to minimize the application by a keyboard buttun such as Esc button...

Is there anybody who can help me to implement minimizing process to system tray by a keyboard button?

Great thanks in forward
