Hello,
I am working on a uninstaller program. Right I'm able to get all the info from the registry on all programs installed using a console application. What I need is a sample list control that will need about 14 columns and any number of row. This way I can display to info on a windows form so that way the user can remove his/her programs.
Just need a little help picking the right component to do this.

I think if you use a datagrid and a custom class, you can bind directly to a list of your custom classes.

Well if those bytes represent the bytes of the Excel file then you just write them to a file. If they are something else then we don't know what they are so we can't help you.

string sfilename = @"C:\\\\test.xls";
FileStream fs = new FileStream(sfilename, FileMode.Create);
xlw.Save(wb, fs);
byte[] binFile = new byte[fs.Length];
fs.Read(binFile, 0, (int)fs.Length);
fs.Close();
return binfile.
Mike the above code returns the byte(right now I am saving the excel file with test.xls in server)
after that i am getting the byte.
client coe:-
-----
byte[]test=webservice.getdata();
FileStream output = new FileStream("C:\\test2.xls", FileMode.Create,FileAccess.Write);
output.Write(test, 0, test.Length);
output.Close();
Test 2 created with the same size as test in server but when i open I am geeting format not good.with empty xls.

Can you open the spreadsheet thats saved on the server before its transmitted to the client?
Something smells fishy about your file saving code. You create the FileStream with FileMode.Create
Then you try to use that file stream to read. I don't think thats the correct way of reading/writing files.
Just because we can; does not mean we should.

I think they create a new file, then xls.Save(wb, fs); writes the actual spreadsheet to the file. After which they read the data back, which shouldn't be a problem i beleive...

Open up both files in xvi32 (or another hex editor) and see if there are any obvious differences, like all the bytes are 00 for example. The most probably place for an error is right at the beggining and right at the end, so check there first.

Is there any possibility to add new files to a msi installer? For Example I have created MyApp.msi ... but I want to add a different configuration file for each client. So I wonder if it is possible somehow to add or replace a file in the msi package without recreating the package. Thanks a lot.

I would believe so based on some Windows Installer work I did back in Versions 1 and 2. Maybe this will help you find a solution.[^]

Hi,
I need to get the Files last Modified Date.Iam given a Zip File by our client on extracting it I get many files, say I got a File A.txt.
whose modified date is 2/19/2008 06:30:00 A.M.
Iam using
DateTime _datetime;
String str = "C:\\A.txt"
FileInfo filinf = new FileInfo(str);
_datetime = filinf.LastWriteTime;
I get the correct output in _datetime.
Now , If I change my System TimeZone from ( GMT +5:30)chennai... to (GMT -8:00)Pacific Time (US & Canada) and then again extract the Zip file to get file "A" with modified date as 2/19/2008 06:30:00 A.M
and execute the same code I get it as 2/20/2008 05:30:00 A.M.
Why is it So?There is an offset of 1 hour.
I need Files Last Modified Date(say here 2/19/2008 06:30:00 A.M only) Irrespective of TimeZones Iam In.
Any suggestions would be appreciated.
Thanks
Satya

I think you should use Globalization For that.
User RegionInfo Class and Try to use the date time from that class.
This is just my idea !!!

I got the solution
FileInfo filinf = new FileInfo(FileName);
_datetime = filinf.LastWriteTime;
DaylightTime dlt = TimeZone.CurrentTimeZone.GetDaylightChanges(_datetime.Year);
_datetime = _datetime.AddHours(Convert.ToDouble(dlt.Delta.Hours));
_datetime = _datetime.AddMinutes(Convert.ToDouble(dlt.Delta.Minutes));
_datetime = _datetime.AddSeconds(Convert.ToDouble(dlt.Delta.Seconds));
Thanks

Hi,
you have a problem with FileInfo.LastWriteTime?
if you read the documentation, you should notice the very next item in MSDN is
FileSystemInfo.LastWriteTimeUtc
Luc Pattyn [Forum Guidelines] [My Articles]

- before you ask a question here, search CodeProject, then Google;
- the quality and detail of your question reflects on the effectiveness of the help you are likely to get;
- use PRE tags to preserve formatting when showing multi-line code snippets.

Use LastWriteTimeUtc instead. The LastWriteTime property is adjusted for timezone and daylight savings time, while the UTC version is not.

Dear gurus,
finally I get totally crazy with interoperability of un/managed code.
I have the unmanged Cpp-Class "MyCppClass" with one simple member-function "add()". This class is not shown here. Now I build a managed wrapper class "MyCppClassWrapper".
I create an instance of this wrapper in a C#-Program and then I want to call the method "add()".
<code>
#include "MyCppClass.h"
namespace Managed {
public ref class MyCppClassWrapper {
MyCppClass *pInst;
public:
int add(int a, int b);
};
}
// implementation
int MyCppClassWrapper::add( int a, int b) {
return pInst->add(a,b);
}
</code>
If I the program starts, I get a FileNotFoundException: "The specified module could not be found. (Exception from HRESULT: 0x8007007E)"
But if I comment out "return pInst->add(a,b);" then everything works fine. It seems that I cannot call the function add() of the pInst-Pointer.
I'm totally lost

The code you posted does not show the pInst member being initialized. You can't use it without initializing it to a valid value.
Oh and this is the wrong forum for your question. This is a C++/CLI question so if you need more information you should ask in that forum.

Anyone know if it's possible to store integers that are < 10 in the 01, 02, 03 format? I have database fields that store hours and minutes in numeric format and I'd like to force the minutes field to be 2 characters in my object so when I display time I don't have to do some nasty if statement and string manipulation to get 1:01 not showing up as 1:1

If you do that then you are storing them as strings. Integers get stored as 32 bit values in binary.

Don't do that in the database it isn't designed for it. Databases are for storing information, not for the rendering of that information.
Also, you also don't need "nasty if statements" you just have to learn how to use string.Format()

Might be a coding horror...but I did this
private String TwoDigit(int x) {
return x.ToString.PadLeft(2, "0"c);
}

You don't store the rendered version of data in a database. You store the actual data. Displaying it in a ceratin format is up to your presentation code, not the database. Using numeric formats to do this is very easy:
Console.WriteLine(String.Format("{0:00}:{1:00}", hours, minutes))
