Could you give me a simple example please? What I want to do is simply to save text to something.txt file from textbox or label on button_click event.

|

ok.. a VERY simple example would be as such: (This is not at all the complete or best way to do it, just a simple example to start your building blocks)
<code>
public void WriteFile(string text, string fileName)
{
System.IO.TextWriter tw = null;
try
{
if(System.IO.File.Exists(fileName))
{
System.IO.File.Delete(fileName);
}
tw = System.IO.File.CreateText(fileName);
tw.WriteLine(text);
}
finally
{
if(tw != null)
{
tw.Flush();
tw.Close();
}
}
}
</code>

Doesn't Close() call Flush() automatically?
|
|
|
|
|
That depends on what you're calling .Close() on. I just find it easier to read, and less "implied", to call it myself, no matter what stream type is in use.

IS there a list of which streams do/don't call it then?
|
|
|
|
|
No. Only if you research each writable stream type.

I think it does currently but you can never tell what they might change in future releases. So I thought it'd be safe to go ahead and call it anyway.
|
|
|
|
|
Thanx for this, I played around with it and it works. What about if I want to load it back to my form?
|

Well, for the simple one line of text in a file you won't need to parse anything. You can simply do just the opposite of what I have above. Check if the file exists but don't delete it. Instead of using File.CreateText you will use File.OpenText. Instead of using System.IO.TextWriter use a System.IO.TextReader. Instead of using WriteLine() use ReadLine(). It's all pretty simple. However, if you're putting multiple lines in the file for multiple objects/properties it does get a little more complex. A more simple way to do this would be to just serialize the label (or whatever other oject you have) into a file and deserialize it back from the file to an object in the code whenever you need it. A good example exists right here on code project:

Hi
Is it possible to set values to a property of a structure in the structure's constructor. For eg.
<br />
struct MyStruct<br />
{<br />
int fieldx;<br />
public int Propertyx<br />
{<br />
get { return fieldx; }<br />
set { fieldx = value; }<br />
}<br />
public MyStruct(int i)<br />
{ Propertyx = i; }<br />
}<br /> This is not compiling whats wrong and why ? But i am able to directly assign the value to the field.
Regards
Deepak

Try this:
<code>
struct MyStruct
{
int fieldx;
public int Propertyx
{
get
{
return fieldx;
}
set
{
fieldx = value;
}
}
public MyStruct(int i)
{
fieldx = i;
}
}
</code>

He did say that he was able to assign directly to the field. He just wanted to know why he couldn't assign to the property.

Ahhh.. I read right over that... Well, you can assign the property as long as you assign the field also. When building a struct constructor, the constructor must not exit until all fields have been assigned. Of course, you're thinking to yourself, "It does get assigned when the property is assigned"... unfortunately the compiler doesn't see that 
|
|
|
|
|
Right. And that's how I answered him.
I can see the logic behind the compiler not looking through the property to see that the field gets initialized. For instance, what if your property setter utilized another field in the struct that hadn't been initialized yet? If you just make it a hard and fast rule of structs that they must have all their fields initialized before you use any of them, then it simplifies the work that the compiler has to do.
There's always reference types.

It looks like, from reading the specification, you're not allowed to utilize any instance members of the type until after it's been fully initialized (viz. all of its consituent fields have been initialized). And since Propertyx is an instance member and fieldx hasn't been set yet, you can't use Propertyx. I could be wrong through. Try setting fieldx and then using Propertyx...see what that gives you.

How can we set the values on the cells for the new row before the RowAdded event gets fired.
For eg if a DataTable has 5 rows, then at this point the CurrencyManager shows a count of 6.
So how can I get a reference of the DataRow that will be added to the DataTable when the currencyManager.EndEdit() gets called.
|
|

|
|
I figured it out.
currencyManager.Current is the one I was looking for.

I want to draw a dashed line
If I call g.DrawLine(....
Is there a way to get the dashes to all be equal length? In other words, sometimes I will draw a line and it will have say, 20.5 dashes instead of
a complete integer number of dashes?
ps- I would like to see code or pseudocode not -- "oh, just use line caps..."
That tells me nothing...
Thanks very much....
|
|

|
|
I'm a little confused... doesn't g.DrawLine take x1, y1, x2, y2?? These coordinates allow you to draw lines to any size you're trying?? What are you having troubles with? 
|
|
|
|
|
Thanks. My problem is when I want to draw a dashed line. What sometimes happens (depending on the length of the line) is that the last dash is cutoff.
So a line has x number of dashes, but then only part of a dash for the last one. It doesn't look very professional....

I'm using VS.NET 2005 Beta 2 and SQL Server 2005 Express to store personal information. The problem i'm facing is the MinDate value of a DateTimePicker cannot be set to below '1/1/2296'. My regional setting on my pc is set to Thailand (Thai year system is +543 from formal year format e.g. year 2005 in formal format is 2548 in Thai format). Also my SQL Server Collation is set to Thai. When i add a date info into the database via my app, it always adds 543 to the year value from DateTimePicker (2548 --> 3091). So the value in the database will always be 543 years over. Could anyone please help me out on this issue?

One quick and easy way (cheating a bit) to fix this is to simple subtract 543 years from the final date BEFORE you enter it into SQL 
|
|
|
|
|
I've tried that before but it didn't work. It seems like it adds 543 just before storing into the db. But when processing, it uses the displayed value. For example, if i try to store a year of 2520, it store 1977. But if i try -543, it says "Out of Range". What a headache... Don't know how to fix it.

Unfortunately I don't know of a fix, perhaps though you can band-aid it on the other side? When you retrieve the data back out, add 543 to it.
