Why did you start a new thread when you already had one about this?

I have a component with COM Interop so its methods can be called from both .NET and COM applications.
I need to do the Windows Service that should do the same and which methods can be called from both .NET and COM. How could I convert this component to service?
Sorry for noob question, I am new with conceptions of Components and especially Services.
Thanks.

I am confused as to what your question is.
A Service is a process (.exe). You can use the component in the Service if that is what you mean.

I've got a multi-tiered enterprise app, that I'm having trouble extending.
I want to build events into my DAL, but can't figure out how to do so without creating a circular reference.
I've got Architecture, DataAbstraction, and Data layers all in seperate DLLs. The architecture layer is simply a factory.
Wherever my events are handled I will need access to the DAL for data. Wherever the events live will need to trigger the handlers.
I can't think of a way to get this done without creating a circle in my references!

You can use an interface to declare the functionality required of your concrete object, code to the interface, and assign an concrete object to the interface member at runtime.

That's the route I've been down in trying to get this working, but I can't figure out how to lay it out. I still get a circle in every attempt I've made.
If "A" has events, and an interface that implements handlers in "B" and "B" needs to reference "A" to do it's job, how do I wire up the interface in "A"? I still need to reference A's dll from B, and vice versa, right?

When I ran into the circular reference issue, I found this page[^], which provided the info I needed. Part of the trick may be in determining which solves your particular situation better:
- A implements IA, and B has an IA member that gets assigned an A, or
- if B implements IB and A has an IB member that gets assigned a B

Hello
I am new to the DLLImport, and I just cant figure out how it works.
I have seen in many other applications they use the DLLImport,
an example is:
[DllImport("KERNEL32.DLL", EntryPoint="MoveFileW", SetLastError=true,
CharSet=CharSet.Unicode, ExactSpelling=true,
CallingConvention=CallingConvention.StdCall)]
public static extern bool MoveFile(String src, String dst);
(found it in the MSDN libary)
Then my questen is how you know what to
write after the [DLLImport ("KERNEL32.DLL",
Is there a place to look it up? or are people just guessing what to write? :
Just to let you know, it is not the KERNEL32.DLL specific i want to know about, just about the dll's in general.
So if anyone know a place where to find this kind of information I would be happy.
Thanks

You can go to pinvoke.net but why are you trying to call an unmanaged function (MoveFile) when you can just use File.Move() ?
|
|
|
|
|
It was just as an example, as it was the only thing I could find, but the pinvoke.net was exactly what I was looking after.
Thanks.

I have an rtf file that I can creating
in some of the sections I am placing contentholders [contenthere] throughout the document.
I need to be able to open up that file and search and replace that [contentholder] with the read data.
The code I used to do this is:
<br />
FileStream swfile = new FileStream(Server.MapPath("") + fPath + filename, FileMode.Open, FileAccess.ReadWrite, FileShare.ReadWrite);<br />
<br />
StreamReader sr = new StreamReader(swfile);<br />
StreamWriter sw = new StreamWriter(swfile);<br />
However, I am able to loop through the document but the original is still there when done.
here is the code I use to actually search and replace:
<br />
while(sr.Peek() >=0)<br />
{<br />
myContent = sr.ReadLine(); <br />
<br />
<br />
if(VB.InStr(myContent, "[PROSPECT]", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent += myContent.Replace("[PROSPECT]", objGCache.GetProspectName());<br />
sw.Write(myContent);<br />
}<br />
else<br />
{<br />
if(VB.InStr(myContent, "{PROSPECT}", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent += myContent.Replace("{PROSPECT}", objGCache.GetProspectName());<br />
sw.Write(myContent);<br />
}<br />
else<br />
{<br />
if(VB.InStr(myContent, "(PROSPECT}", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent += myContent.Replace("(PROSPECT)", objGCache.GetProspectName());<br />
sw.Write(myContent);<br />
}<br />
}<br />
}<br />
<br />
if(VB.InStr(myContent, "{CONTACT NAME}", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent += myContent.Replace("{CONTACT NAME}", objGCache.GetContactName());<br />
sw.Write(myContent);<br />
}<br />
<br />
if(VB.InStr(myContent, "{ADDRESS}", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{ <br />
myContent += myContent.Replace("{ADDRESS}", objGCache.GetAddress1());<br />
sw.Write(myContent);<br />
}<br />
<br />
if(VB.InStr(myContent, "{CITY, STATE ZIP}", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent += myContent.Replace("{CITY, STATE ZIP}", objGCache.GetCity() + "," + objGCache.GetState() + " " + objGCache.GetZip()); <br />
sw.Write(myContent);<br />
}<br />
<br />
if(VB.InStr(myContent, "[WWH]", Microsoft.VisualBasic.CompareMethod.Text) > 0)<br />
{<br />
myContent = myContent.Replace("[WWH]",newcontent);<br />
sw.Write(myContent);<br />
}<br />
<br />
<br />
<br />
<br />
<br />
}<br />
Sorry for the length and bad formatting, dont have time to look all pretty 
If anyone could give some advice asap, that would be greatly appreciated.

You are using += instead of = when assigning the result of the replacement to the string. That means that you are creating a new string by concatenating the original string with the replaced string.
You should do all the replacements first, then write the resulting string to the StreamWriter. If you write the string after each replacement, if the line contains more than one content holder you will be writing the line several times, and only the last one fully processed.

Thanks for the reply Guffa,
So you are saying that what I have there should work fine I just need to stop adding to the string by using += and just use =, but the rest of the code seems viable to you?
I will change that and see if it makes a difference. Thanks for your time.

oh yea I caught that and just wanted to make sure that was the only thing you saw wrong with the code. I will try this when I get a chance, caught up in another project at the moment. Dont you just love deadlines..*sigh*

Hello,
I'm using the following code to get the number of rows in an Excel worksheet.
range = (Excel.Range)excelWorksheet.Columns["A", Type.Missing];<br />
range = range.get_End(Excel.XlDirection.xlDown);<br />
Console.WriteLine(range.Row.ToString());
It works fine with any number of rows (I've tried up to 2000), however if my worksheet has 1 row in only it returns the total number of rows - 65536. Any suggestions?
Thanks in Advance
Jonny

Hi Everybody,
Can anyone tell me how we can calculate working hours base on two intervals of time.
like
Starting Date: 17-05-2006 09:00 AM - Ending Date: 17-05-2006 05:00 PM ?
If ending date something like this then what to do?
Starting Date: 17-05-2006 09:00 AM - Ending Date: 18-05-2006 08:00 AM
I'm using C#.Net
