Hello everyone.
How can build an exe file by VS .NET to execute it on Windows_98?
Thank you![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

If this is a .NET assembly, just make sure the .NET Framework is installed on the client's machine. If you built an unmanaged VC++ project, there are countless things you must insure. To name a few of the biggies:
- Make sure you're not using Unicode methods without the Unicode layer for Win9x
- Make sure you're not using methods that only work on Windows NT (such as the Network Management API or the GINA methods)
- If you do use Unicode, make sure you make two builds: 1 for ANSI and 1 for Unicode. Make sure you install the appropriate build on the appropriate platform.

I've got a huge database table (near 50000 records) and I want to use a ComboBox to select one of this records. First, I've used a DataSet like this :
<br />
DataSet ds=LoadArticlesDataSet();
this.comboArticles.DataSource=ds.Tables[0];<br />
this.comboArticles.DisplayMember="code_ne";
But the data loading was too long :
- LoadArticles took 3/4 seconds
- this.comboArticles.DataSource took 3/4 seconds
- this.comboArticles.DisplayMember took 3/4 seconds too.
To reduce the combo's time loading, I chose to construct the ComboBox at the start of the program in another class named CDataBase :
<br />
public FArticle(CDataBase db)<br />
{<br />
InitializeComponent();<br />
this.panel.Controls.Add(db.comboArticles);<br />
}<br />
Unfortenately, the first form's painting still takes 4/5 seconds.
Do you have a solution to make the ComboBox faster or do you know another control which could be used instead of the standard one ?
For example, Have you ever seen an Access-like combo control which shows only a part of its items and has an auto-completion ?
Thanks !

I hope this is the right forum for this question.
I have several functions written in VBA that I use as Add-ins to Excel 2002 (v10). Several variations require iterations to solve so I want to modify these functions in C# and create several DLLs. I have created and built a DLL in C# for a coupled of simple functions that work when called from a console project. I have added a reference to C:\WINDOWS\assembly\GAC\Microsoft.Office.Interop.Excel\10.0.4504.0__31bf3856ad364e35\Microsoft.Office.Interop.Excel.dll in class module (dll) project. I want to have the users load/unload the Add-ins through Tools | Add-in dialog.
How do I now register this dll in Excel? Do I have to create a wrapper in VBA? Does anyone have an example?
Thanks

I'm told that every c# application can be easily decompiled into source (and not crappy c++ decomilation, but nice readable code). So basically all the apps you write will be open source, not in the legal sense, but in the physical sense. Everyone I know who writes c# is either starting to face this issue or admits that he'll have to eventually. Seems to me this should have been part of VS.net.
What are you doing about it? I've heard there's going to be an obsucator out for C# that will cost like $1000, does anyone know of any others? I couldn't find articles about it here on codeproject...
Or do an of the MS guys know if MS will add obfuscation into vs.net?
thanks

Dotfuscator claims that Microsoft will be using a community edition of their production in VS.NET.
Thanks,

Like Wesner said, the 2003 version of Visual Studio will contain a community version of "Dotfuscator", but you can already download it now.
I, too, am very worried about decompilation of my work. Anakrino makes it very easy to decompile any .net assembly function/type. With a little work, source code for an entire assembly can be reproduced from the DLLs and EXEs! Obfuscators will only slow down this process, but not disable it.
Any solutions appreciated...

Does anyone know if it is possible to get to the raw socket for the connection associated with an HttpRequest when writing an HttpHandler ?
|
|
|
|
|
The internal Socket connection is managed by the System.Net.Connection class. Unfortunately, there is no way to get this connection from the public properties of a current HttpWebRequest instance. You have to derive from this class.

hi,
beside a listbox,I put two buttons, one with up arrow icon, and one with down arrow icon.
I wish the selected item can be move up or down by pressing one of two buttons, for example,
there are 4 items in listbox, item1,item2,item3,item4, after selected item2, and press the up arrow button a time,the order become item2,item1,item3,item4, and if press the down arrow button three times,the order is
item1,item3,item4,item2.
and how can I do that?
thanks for any idea.

i have a clock function going . it is started by a seperate thread at the application startup
it works like this
while(myThread.IsAlive==true)
{StatusBarPanel.Text = DateTime.Now.ToString();}
it works but i want a more effientway (it eats too many cpu cycles) i tryed using timers.. i tryed reading the documentation but i cant seem to figure it out .. can someone PLEASE help me ? i dont understand i can import dll's all kinds of stuff.. but something as simple as this haunt's me. its got me up nights !!
Additional my program launches a recursive search agian with a new thread but set to the ThreadPriority.Highest Level i would like too disable this(clock) during that search.

I guess that would be the stack size limit.

Well, you could increase the size of the stack, don't know what the limit is with .NET, on the other hand, I never came across a recursive function *that* recursive
And remember that there is always a perfomance hit on each function call.

What do you mean by that? I have seen no difference between running it in a while(true) loop vs a recursive function.
Yes, the difference is very small, you should measure it in millisecons.
Every recursion makes a call to a function, there's a small penalty there. If you are using a virtual method is a little bit bigger (big as in really small )

Problem:
I can't seem to catch any file or directory activity events for IIS's log files.
I have seen this problem behavior before with both NT Shell Hooks and .Net FileSystemWatcher code (which I assume is basically hooking into the same NT event mechanisum)
Basically, I want to "scan" IIS logfile activity whenever a website is browsed.
I could use ISAPI filters but really wanted to just be "alerted" each time someone
hit's the site using FileSystemWatcher code.
But it don't work. How can one "watch" an (I assume) in memory file ???
Any ideas ???

This isn't the right way to do this for so many reasons.
First, because IIS writes logs to memory and batches a write operation from time to time (for which the actual file doesn't often change because enough space is allocated for several batch writes).
Second, you're right: ISAPI is a better solution; however, if you are interested in ASP.NET pages (after all, do you really want to know each request for an image, "robots.txt", "favicon.ico", etc.?), you can easily write an IHttpHandler that will write a custom log for you somewhere or use remoting to update a chart in a different application.
There is yet another option that already exists and one which you could extend: performance counters. If you look in your Computer Management MMC snap-in (right-click on "My Computer" and select "Manage..." for easy access), you'll see an extension for logs. You could start by creating your own log file there for this specific purpose. You can also see this in "perfmon.exe" for which you can setup new counters. The .NET Framework has good support for counters, too, so you can take advantage of the file in many ways.
Third, as I touched upon before, you don't want to be notified for requests to things like "robots.txt", "favicon.ico", and all the various spiders do you? If you're interested in legitimate hits to your *pages*, the IIS log will never tell you that unless you plan on parsing a very large file yourself every time it changes.

Thanks for your input.
I didn't think of the PerfMon approach which seems to be as un-intrusive as one could
get which is what I was shooting for.
I will try out your suggestion.
Thanks again for your time.

In Java, you can say:
if (obj instanceof java.lang.String)
{
}
What is the C# equivalent, if any?
