The only way you can use CSS to control a winform app layout is if your presentation layer is a browser control, and your apps backend emits html; instead of using the standard winform controls. 
Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

you can not use css in windows application
|
|
|

You can't use CSS with a standard winforms application, but you can achieve an effect similar to CSS if you use WPF, because CSS is used to style web pages - and you can style WPF apps[^].

And, XUL. XUL can be styled with CSS.

HI
I have a table (ContactDetails) with 2000 records. I have an application receiving an XML file from an external web service. Most time the data received from the web service is similar to the data in my table. Occasionally the data returned from the web service will have few differences. I want to compare the data received from the web service with the data in my local database and generate a xml file (based on the same schema) to send to another application. So how do i go about do that?

Hello!
It is only a part of my source code:
//******************
private void button2_Click_1(object sender, EventArgs e)
{
openFileDialog1.Title = "Choose image to convert:";
openFileDialog1.FileName = "";
textBox1.Text = "";
//shows dialog
openFileDialog1.ShowDialog() ;
//receiving name
CurrentImage = openFileDialog1.FileName;
if (CurrentImage != "")
{
img = Image.FromFile(openFileDialog1.FileName);
//drawing picture
pictureBox1.Image = img;
textBox1.Text = CurrentImage;
//******************
When i am choosing an easy picture(*.tiff extension,size = 474 kb,dimensions:1920*1200) everything is ok, i mean that this picture is displays at my form.
But if picture is more hard(*.tiff extension,size = 10.9 mb ,dimensions:56304*13384) i have such error: Out of Memory(indicates the next string of source code Application.Run(new Form1());)
What i have to do to solve this problem.
Thanks.

The "Out of Memory" part of the error isn't a clue?

Why would you want to display an image with that resolution on a form

You mean with first simple resolution? How i can to convert resolution from hard to simple without loading picture to c# studio?

Get a better CPU and add some more RAM, upgrade the video card, etc.

Hi
I have a piece of code that retrieves Oracle connection information and places it in a list box.
string ProviderName = "Oracle.DataAccess.Client";
DbProviderFactory factory = DbProviderFactories.GetFactory(ProviderName);
if (factory.CanCreateDataSourceEnumerator)
{
DbDataSourceEnumerator dsenum = factory.CreateDataSourceEnumerator();
DataTable dt = dsenum.GetDataSources();
foreach (DataRow dtvar in dt.Rows)
{
listBox1.Items.Add((dtvar.ItemArray[0].ToString() + " : " +
dtvar.ItemArray[1].ToString() + " : " +
dtvar.ItemArray[2].ToString() + " : " +
dtvar.ItemArray[3].ToString() + " : " +
dtvar.ItemArray[4].ToString()));
}
}
else
{
MessageBox.Show("Enum not provided by provider");
}
This works on one machine which adds lines like "DB1 : MYMACHINE : db1.domain.local : TCP : 1521"
but on another machine (with the same TNSNAMES.ora) gives "DB1 : : db1.domain.local : :"
i.e. the host name, protocol and port are not being retrieved.
Both machines have the same Oracle client (10g) and the same Oracle.DataAccess.dll (2.111.6.20)
Any ideas what could be different between the machines or what is causing the problem?

Few questions:
- is the ...\NETWORK\ADMIN\TNSNAMES.ORA-file identical in both machines
- is the ...\NETWORK\ADMIN\SQLNET.ORA-file identical in both machines
- is TNS_ADMIN defined in environment variables identically in both machines (or not defined at all)
- is TNS_ADMIN defined in registry (HKEY_LOCAL_MACHINE\Software\Oracle\HomeName) identically in both machines (or not defined at all)
- can you successfully connect to the db. If not what is the ORA-error

Hi
Thanks for the help.
The TNSNAMES.ORA file is identical on both machines and we copied the working one to the other machine with no effect.
The SQLNET.ORA is also identical.
Both machines are missing a TNS_ADMIN environment variable and both machines are missing the registry entry for TNS_ADMIN.
Both machines can connect to DB using c# normally.
As a correction in my question, the working machine is using Oracle 11 client whilst the non-working machine is Oracle 10g client.
Thanks

If I have understood correctly, Oracle 10g client reports TNS-entries differently than version 11. If the connection is established without errors, do you still want to resolve protocol and port to the list?

Hi all, I'm having a hard time getting my head around this() and base(), hoping someone can help.
Let's say I have classB which inherits classA both have a constructor and an overloaded constructor.
class classA
{
public classA()
{
}
public classA(int i)
{
}
}
class classB
{
public classB()
{
}
public classB(int i)
{
}
}
How do I get the overloaded constructor of classB to first call the default constructor of classB and then the similar overloaded constructor of the base class, classA? I seem to be able to have it call either the default constructor of classB OR the overloaded constructor of classA by declaring the overloaded constructor of classB as
public classB(int i) : this()
or
public classB(int i) : base(i)
but how do I get it to call both?
|

|

First of all the proper way to inherit is :
public ClassB:ClassA
{
}
Secondly, when you are instianting ClassB it calls the parent constructor first and then instiante the derived class. For instance
ClassB cb = new ClassB()---> it calls the Parent no value(default constructor) first and then
public classB()
{
}
Thirdly, ClassB cb = new Classb(2)-->it calls the Parent value constructor in ur case is
public classA(int i)
{
} and then the dervied class constructor
public classB(int i)
{
//some code
}
hope it may help
|

Are you sure about that second case? As far as I understand (and can reproduce), if you instantiate ClassB cb = new ClassB(2) it calls the default constructor of ClassA first and then the overloaded constructor of ClassB. It never calls the overloaded constructor of ClassA as you say.
This is of course if you don't specify for the constructors whether they should be calling other constructors. If I wanted the overloaded constructor of ClassB to first call the overloaded constructor of ClassA as opposed to the default constructor of ClassA, I would have had to specify it as:
public ClassB(int i) : base(i)
{
}
Am I missing something?
|

|
|

Try the following:
class classA
{
public classA() : this(0)
{
}
public classA(int i)
{
}
}
class classB : classA
{
public classB() : base()
{
}
public classB(int i) : base(i)
{
}
} With this, calling the classB constructors will result in the appropriate classA constructors being called. If however, you want to explicitly perform some code in response to the constructors, I would create an OnInit method, and call it from public classA(int i). This means that all of the paths through to it will be handled.

I think the call to base() is not needed here. When classB is instantiated, parameterless constructor of base class will be called.

Thanks, but this won't exactly do what I'm looking for. I'm looking for a way to have an instantiation of ClassB cb = new ClassB(1) make a call to both constructors of ClassB as well as the default constructor of ClassA.
The way you suggest would result in an instantiation as above to only call the overloaded constructors of both classes, but not the default onstructor of ClassA.
Not to worry though. The more I think about it, the more I realise that I'm trying to use OOP in a way it's not meant to be used. I've found another way to achieve what I want anyway.
Also, I think your suggestion of an OnInit method makes better sense as well.
Thanks again.

but how do I get it to call both?
You don't, cause you can only have on base instance, so you can't call two constructors. You'll have to put the code from both base class constructors into two protected methods and call each from the respective base class constructor, and call both from the derived class constructor.

Makes sense. I realised afterwards that this is really what OOP is all about. Thanks for the response.
