I got interested in Web Services and found an article at http://www.codeproject.com/cs/webservices/cpwebserviceconsumer.asp; it references http://www.codeproject.com/webservices/latest.asmx, but I get a parser error; is this web service down or has the URL changed? Thanks

i have gone through the interop services and what i have analysed is
---------------------------------------------------------------
.net interop services offer support to integrate c-style dlls into your c#
code i mean managed code,
but not same for unmanaged c++ class libraries. if you want to make calls
into an unmanaged c++ class library, you definitely have to write a
wrapper class, and you have to write it in managed c++.
i think there is no other way out.
----------------------------------------------------------------------
now problem is i have (mfc + c++) libs & dlls only. i dont have the code
with me. so i can't write wrapper classes.
so could u suggest any other way around.

Try creating a COM object that's calling classes from your dll's.
That way you can easily add a COM reference to your newly-created class and then use this one to access your legacy classes.

In WinForms programming I made 3 Forms.
and the 3 forms have same menu but the menu load all forms each of menu item.
So I think I want to make it does not take more resource when hide a form and show another form.
So I made write down like this...
class Form1
public Form2 form2; Form3 from3;
Form1()
{
form2=new Form2();
form3=new Form3();
}
and like above in another form.
it makes a recursive function and resource take more and more, it can't show main screen. constructor has all resource, it is not I want.
then I copy some code that is using owner but It has some more and more resource when I open file and close file.
I can't use form1.Close it will shut down my program. then I can't get resource when I hide a form.
menu can bring any another form of my program and then hide or close using form.
I must implement it. but I'm a beginner. So I want kind explain.
thanks you for reading.
Image will remind us some feelings and if I can ask someone about a problem, that's not a bad life.

Hi
Can you try solving your problem using MDI form. Create a MDI form and make your forms as child's of it.
You can make a form as MDI form by setting its IsMdiContainer property to true.
You can make your forms form1, form2, form3 as child forms by setting their MdiParent property to object of your MDI form.
Guess this solve your problem
If you need more help let me know.
Thanks.

Hi,
In a text change event I am loading a list of suburbs based on the user input. When i clear the combobox items I loose the text as well. When I reset the text it calls the change event again and I get a loop happening. How can I clear the items without loosing the text in the box? OR What is a better way than using the text changed that will not be triggered when i write the text back?
Thanks for any help.

hi,
Better you need to store the selected value to some temporary string variable.
Like string TempString=Combo1.Text;
Then try to clear the items.;)

while writting WMI application, i could read many values by means of System.Management namespace.
many examples show how to read the values in Win32_class.
my question is : How to modify the value in Win32_class using System.Management namespace ?
there are some methods which might do this work such as Put(), SetPropertyValue(). But How to use them ?

I'm using Media Player to play media files, and my problem is getting it to play multiple files where my code does the queuing. I get a medaEnded message, but if I queue another file, it doesn't play. Does anyone have any ideas ?
And anyone who suggests DirectX will be shot. DX9 is an absolute joke, that's why I'm trying to get the core of my app working with Media Player 3 days before I deliver the application.

Hello Gurus,
I deployed a windows-based applications with some crystal reports on client machines. Running the reports popped up the following error on client machines.
Error: Cannot find KeycodeV2.dll, or invalid key
Where can I find the "LicenseKey" tag to enter my registered key code?
Thanks gurus, with another $million,
Khang
===================================================================
Crystal Reports Rep. gave me the following instructions but I could not find it at all:
This error may occur if the LicenseKey value is not entered. Kindly follow
the steps given below to enter the value:
* Right click "Project" in the Solution Explorer
* Click "Add" and then "Merge Modules".
After clicking "Merge Modules" it will have a property "LicenseKey" in which you can enter the value.

When you first started the Crystal Reports tool in Visual Studio .NET, it prompted you to register. This email - per the instructions on the screen when you finished registering - includes your registration information that needs to be entered to use the designer, as well as the Crystal_regwizXXXX.msm merge module if you're building a Windows Installer project.
Read Deploying Crystal Reports in .NET Applications[^] in the Visual Studio product documentation.
If you're using the standalone edition, you need to read the instructions for the steps required to accomplish what I outlined above. I doubt that it's very different, and the merge modules should be the same.

Hello Heath,
Thank you so much for replying so quickly. Yes, I already registered my Crystal Reports product for MS Visual Studio 2003.
As I understood from the Crystal Reports Rep., after adding the merged module "Crystal_regwiz2003.msm" to the Setup Project, I will have a KeyCode tag to enter my registered key code. However, I could not find this tag any where. And I still get that run-time error.
Thanks,
Khang

In Visual Studio (or whatever you're using to create your Windows Installer package), select the Crystal_regwiz2003.msm merge module. In Visual Studio, right click and select Properties. This displays the PropertyGrid. In there is a custom property that should be obvious. I don't have this machine set up for that right now, but - like I said - it should be obvious.
Set the property value ot your key code, recompile the package, and redeploy it. This is also covered in the documentation for which I gave you a link.

I got it. It was hiding under the "MergedModuleProperties" tree. I expanded the tree and saw that property.
You're great, Heath. I guess life is very sweet at Microsoft?
Thanks so much

Hi,
I have a file which contains 13726 names on a text file (my school's students' names). Every line contains one name. And I have a textbox on a form which gets the name of the file and when I press the button it has to make seperate files which has 300 names in it. I mean I have to seperate these 13726 names on different files which has must contain 300 names and the last one must have 276 names in it. I made my button's function like below:
<br />
private void button1_Click(object sender, System.EventArgs e)<br />
{<br />
int a=1; int b=1; int k;<br />
StreamReader re = File.OpenText(textBox1.Text.ToString()+".txt");<br />
string input = null;<br />
ArrayList arrText = new ArrayList();<br />
while ((input = re.ReadLine()) != null)<br />
{<br />
arrText.Add(input);<br />
if(a%300 == 0)<br />
{<br />
FileInfo t = new FileInfo(textBox1.Text.ToString()+"_"+ b + ".txt");<br />
StreamWriter Tex = t.CreateText();<br />
for(k=(b-1)*300;k<(300*b)+1;k++)<br />
{<br />
if(k==0)<br />
{<br />
Tex.WriteLine(arrText[k+1]);<br />
}<br />
else<br />
{<br />
Tex.WriteLine(arrText[k]);<br />
}<br />
}<br />
Tex.Write(Tex.NewLine);<br />
Tex.Close();<br />
}<br />
a++;<br />
}<br />
re.Close();<br />
}<br />
but I couldn't get a result so any help would be greatly appreciated...
Thank you,
Cem Louis
