LPARAM is a C/C++ type defined & used by Windows for passing values with messages, it has nothing to do with USB devices. Also, does you question relate in any way to C#?
Use the best guess

|

yes. I'm overriding WndProc method to catch unplugging & plugging of the usb device. However is that the LParam is acquired in this WndProc process. When the software launches, the LParam for each device isn't acquired.
Also I was thinking of the other way around to get that is by restarting the usb devices at startup to trigger "unplugging" and acquire LParam. Unsure of the way to do this either.

Another guessing game! I have no idea what message you are trying to process, nor what values you should be receiving when the device changes status. And as I said before, devices have no concept of LPARAM .
Use the best guess

|

I assume your software is watching for WM_DEVICECHANGE messages where WParam is either DBT_DEVICEARRIVAL or DBT_DEVICEREMOVECOMPLETE. LParam will then point to a device dependent structure, related to DEV_BROADCAST_HDR, containing device information.
Windows Management Instrumentation can probably provide similar information for connected devices but without knowing their type and the information you need it's impossible say more.

public string HTMLToPdf(_TableProperty ReportProperty, string FilePath,Stream stream)
{
string htmlread2 = getReportHTML(ReportProperty, stream);
Document document = new Document();
PdfWriter.GetInstance(document, new FileStream(System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "\\myPDF.pdf", FileMode.Create));
document.Open();
iTextSharp.text.Image pdfImage = iTextSharp.text.Image.GetInstance(System.Web.HttpContext.Current.Server.MapPath("pdfic.jpg"));
pdfImage.ScaleToFit(100, 50);
pdfImage.Alignment = iTextSharp.text.Image.UNDERLYING; pdfImage.SetAbsolutePosition(180, 760);
document.Add(pdfImage);
iTextSharp.text.html.simpleparser.StyleSheet styles = new iTextSharp.text.html.simpleparser.StyleSheet();
iTextSharp.text.html.simpleparser.XHTMLWorker hw = new iTextSharp.text.html.simpleparser.XHTMLWorker(document);
hw.Parse(new StringReader(htmlread2));
document.Close();
ShowPdf("myPDF.pdf");
return htmlread2;
}
private void ShowPdf(string s)
{
System.Web.HttpContext.Current.Response.ClearContent();
System.Web.HttpContext.Current.Response.ClearHeaders();
System.Web.HttpContext.Current.Response.AddHeader("Content-Disposition", "inline;filename=" + s);
System.Web.HttpContext.Current.Response.ContentType = "application/pdf";
System.Web.HttpContext.Current.Response.WriteFile(s);
System.Web.HttpContext.Current.Response.Flush();
System.Web.HttpContext.Current.Response.Clear();
}

I reckon it's the parameter to the method ShowPdf(String filename) that propably needs the full path. Otherwise the Request.WriteFile method won't be able to locate the file. Construct the full file path analogous to the stuff you did for the FileStream:
String fullFileName = System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "\\myPDF.pdf";
then use fullFileName for both the FileStream creation and the call to ShowPdf .

How about when the form loads? That'd select them all, even before the list is shown.

If you can't read my code, try converting it here[^]

set MultiSelect property true and checked list item in loop.
|
|
|
|
|
If I'm interpreting your question right you want the user to be able to select all of the items in the ListView, but you don't want to give them a button to do it? If so, why not set up a context menu with a Select All option? Then, as others have suggested, step through all the items in the LV and set Checked = true; for each item.

Hello
I have to separate lists containing two columns: Dates - Values
One of the lists have all dates from startdate to enddate, while the other list is missing weekends and holidays. So this missing holes I need to replace by the value from day before and then add these values to a new list with all dates in one column, and then values-list1 and values-list2 in two next columns...
public override void OnShutdown()
{
string[] row = new string[7];
double Close;
string currentLine;
long dates_in_IQB;
for (int i=0;i<AccountHistoryCount(0);i++){
dates_in_IQB = (long)AccountHistoryDateTime(0, i);
DateTime newDate = new DateTime(dates_in_IQB);
OutputWriteLine(String.Format("Date {0}", newDate));
}
using (StreamReader sr = new StreamReader("d:/documents/SPY Ref1.csv")){
sr.ReadLine();
while((currentLine = sr.ReadLine()) != null)
{
row = currentLine.Split(',');
DateTime Date = DateTime.ParseExact(row[0], "dd.MM.yyyy", null);
Close = double.Parse(row[6]);
}
}
}
I'm pretty new to the programming, so I guess I need the information down to every details.
Kind regards
Espen

You're out of your mind if you think we're going to do your homework for you.

if you have nothing to help. GET LOST! i dont need your comment

I've been active around here for 10 years.
The way you worded your question makes it seem like you want someone to write your code for you and supply you with exactly what would be required for a homework assignment.
The quality of the question directly dictates the quality of the answers you get.

Using the MD5 class is not that hard. There is even a sample in the MSDN documentation. Have a look here: MD5 Class[^].
Try to do this assignment on your own. You'll probably find that it really isn't all that hard to do.

thanks though. i just figured it out at last! ^_^ . It's just my first time to encounter such kind of program

What? As soon as you embed the hash value of a previous calculation, you change the program. And consequently, the hash value is no more the same.

What exactly did you mean by writing: "The program must have an actual and expected output embedded in the program." ?
You'll have to explain that a bit more.
Cheers!

their should be actual and expected output in the program. no need to input. btw nevermind. i just figured it out at last
