Problem printing images on Zebra Printer

Hi,
I am working on a Zebra Printer (110XiIII Plus) and trying to print custom labels using a C# application, but am having no progress in printing graphics i.e. images. I am using the latest driver also.

I have a BMP file that needs to be printed. I tried to print using the PCX format, but even that didn't work.

I read in the documentation that the ~DY command can be used to send a bitmap to the printer and then recall it from the printer's memory and print it.But even that hasn't worked.

The command I am using is ~DYE:123.BMP,B,B,4096,,
Where 123.BMP is my file which is 13x13 and 4096 is the size in bytes. Is this correct or am i missing something or doing wrong!??

Any help is appreciated.

Regards
Sharath M

First off Zebra printers are kind of a pain, but they do work pretty good. I guess my first question would be have you loaded the 123.bmp on the zebra printer? In my previous job, there was a lot of custom code to load all the images onto the zerbra so those commands would work. My current job, we use crystal reports and embed images into the report and that seems to work just fine.

Hope that helps.

No API needed!

Just override WndProc method like this:

const int WM_SYSCOMMAND = 0x112;
const int SC_MAXIMIZE2 = 0xF032;
protected override void WndProc( ref Message m )
{
    if( m.Msg == WM_SYSCOMMAND )
    {
        if( m.WParam.ToInt32() == SC_MAXIMIZE2 )
        {
            return;
        }
    }
    base.WndProc( ref m );
}

Hope it helps!

If you talking about C# you do not need API for this, just set to false the MaximizeBox property for the Form object. Wink | ;)

TreeView expand

collapo1-Aug-07 0:22

I've a simple function:

<code>
private void BuildTree()
{
TreeNode rootNode = new TreeNode("Root");

TreeNode node1 = new TreeNode("Child 1");
TreeNode node11 = new TreeNode("Child 11");
TreeNode node12 = new TreeNode("Child 12");
node1.Nodes.Add(node11);
node1.Nodes.Add(node12);
rootNode.Nodes.Add(node1);

TreeNode node2 = new TreeNode("Child 2");
rootNode.Nodes.Add(node2);
TreeNode node3 = new TreeNode("Child 3");
rootNode.Nodes.Add(node3);

treeView1.Nodes.Add(rootNode);

if (!rootNode.IsExpanded)
{
rootNode.Expand();
}
}
</code>
My problem is:

If I create a new Winforms application, the expand function does its work, but if the same function is written into a .dll where the treeview is on a usercontrol, expand does nothing. I mean the node doesn't expands so I have to click on '+' to do it.
I use the same function at each time.
Any guess?

Just a guess but the difference may be at what point you call this function. Probably your test app already shows the treeview when calling the function while your usercontrol calls the function before the tree is visible.
I don't think it has anything to do with the user control as I already used Expand on TreeViews within user controls.

The treeview is shown in initializecomponents in both project, if I'm not mistaken, therefore that can not be the problem. The function is called right after Initializecomponents(), so it is called "at the same time".
But anyway thanks, I'm waiting for others.

And the winform application is not a test, but a paralell application.

memory problem with releasing excel object

S Palip31-Jul-07 23:45

Hi,

The following is the code i used to create, write to and save an excel file. Everything goes fine except there is a delay in releasing the object. Yes it persists till the application is closed. Sometimes i'm able still see the excel.exe in the task manager even after the application is closed. Is there any way to overcome this.

I've added a reference to excel 11.0 com component.

private void CreateExcel()
{
Excel.Application ExcelApp = null;
Excel._Workbook ExcelWorkbook = null;
Excel._Worksheet ExcelWorkSheet = null;
string strSavePath = "";
try
{
ExcelApp = new Excel.Application();
ExcelApp.Visible = false;
ExcelWorkbook = (Excel._Workbook)(ExcelApp.Workbooks.Add(Type.Missing));

ExcelWorkSheet = (Excel._Worksheet)ExcelWorkbook.Sheets["Sheet1"];
// ExcelWorkSheet.Name = "My Sheet";

//Make sure Excel is visible and give the user control
//of Microsoft Excel's lifetime.
ExcelApp.Visible = false;
ExcelApp.UserControl = false;

/*********************/
DataSet dsData = MyDataLayer.GetDataSet("Select top(3) from XXXX");

if (dsData != null && dsData.Tables.Count > 0)
{
// the writing process
ExcelWorkSheet.Cells[iRowIndex, iColumnIndex] = data;

}
/*********************/
//ExcelWorkSheet.get_Range("A3", "F3").HorizontalAlignment =
//Excel.XlHAlign.xlHAlignCenter;

//ExcelWorkSheet.get_Range("A1", "A1").Font.Bold = true;
ExcelWorkSheet.Visible = Excel.XlSheetVisibility.xlSheetVisible;
ExcelWorkSheet.Activate();
ExcelWorkSheet.get_Range("A3", "F3").EntireColumn.AutoFit();
//ExcelWorkSheet.get_Range("E1","E1").Columns.EntireColumn.NumberFormat = "£###,###,##0.00";

strSavePath = Application.ExecutablePath.ToString();
strSavePath = strSavePath.Substring(0, strSavePath.LastIndexOf("\\"));
strSavePath = strSavePath + "\\TestExcelFile.xls";

ExcelWorkbook.SaveAs(strSavePath, Excel.XlFileFormat.xlExcel7, Type.Missing, Type.Missing, Type.Missing,
Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
// ExcelWorkbook.Close(false, strSavePath, null);

// return;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
if (ExcelWorkSheet != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelWorkSheet);
ExcelWorkSheet = null;
}

if (ExcelWorkbook != null)
{
ExcelWorkbook.Close(false, strSavePath, null);
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelWorkbook);
ExcelWorkbook = null;
}

if (ExcelApp != null)
{
ExcelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelApp);
ExcelApp = null;
}
}
finally
{
if (ExcelWorkSheet != null)
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelWorkSheet);
ExcelWorkSheet = null;
}

if (ExcelWorkbook != null)
{

ExcelWorkbook.Close(false, strSavePath, null);
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelWorkbook);
ExcelWorkbook = null;
}

if (ExcelApp != null)
{
ExcelApp.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(ExcelApp);
ExcelApp = null;
}

//GC.WaitForPendingFinalizers();
}

GC.Collect();
}

Thanks,

PLS Smile | :)

I have also run into this problem some time ago. The only solution (workaround) I found was to get a list of all running processes (Process.GetProcesses) before creating the Excel.Application instance and then again after the creation to fetch the corresponding process. I then killed this process after being done.
I know this is completely insane but as said I didn't find any other solution.

Hi All,

I am using FolderBrowserDialog in my application. FolderBrowserDialog have RootFolder Property, where it gets or sets the root folder where the browsing starts from. But we can assign only SpecialFolder to RootFolder.
Is it possible to assign user specified folders other than special folders?

Is there any other dialog where we can achieve this?

Thanks in advance.
