Hi John, I think I have a partial answer for you: within a WinForm app, when you create a bitmap and then a Graphics from that, you get a Graphics that is compatible with your screen, so e.g. you could use MeasureString and get (pretty) accurate predictions for when you are going to draw some text in the Form.Paint handler.
AFAIK it does so by guessing which monitor you are on (when you have more than one that is). I never did any such thing in ASP.NET, I guess it does not have a (relevant) monitor around for you, so its properties could be way off; you might have a look at DpiX and DpiY (they are getters only!).
I don't know the solution right now; a little Google action pointed me here[^], maybe that helps.

He's not doing anything I'm not doing (and I'm doing even more). I've tried everything from a minimalist approach to full on high-quality settings, and nothing seems to affect the appearance of the image. Even Silverlight/WPF does a better job at rendering text...
I'm getting kind of annoyed at the whole thing...

Here is one idea: replace Transparent by White, just to see if that gives decent quality. I never trust Windows and transparency, it holds too many surprises.

Even if it displayed better, I need the background to be transparent.

IMO making a little step sidewards is often useful in a debug session, even when it violates functional specs.

At this point, I'm tempted to just create the graphics with photoshop and call it a day.

Well, it does in fact ONLY happen when I use g.Clear(Color.Transparent). That's a real pisser because now I have to do a screen cap of the gradient background we use in the Silverlight app so I have a non-transparent image to render the text onto. What a pain in the ass... and all because a) Silverlight's element rotation f*cks up your layout, and b) it doesn't allow you to build images on the fly.

From everything I read about it over the years, I gathered transparency on Windows is a PITA. I try and stay away from it as much as possible.
Thanks for reporting.

I've observed that it works fine in Winforms, but it sucks in asp.net

you may want to repost in ASP.NET forum then; and probably add a sample of each.
Did you notice anything different in the properties of both Graphics objects? From what you told so far, it isn't clear to me yet whether this indicates a bug or something you overlooked.

Complaints are many regarding he quality of text rendered on a transparent bitmap. The one thing I haven't tried yet is creating a transparent bitmap disk file, loading that in the asp.net page code behind, and rendering text on it. I can tell you that creating the (transparent) bitmap in code and rendering text onto it creates a crappy looking image. IMHO, it's a bug.

In the interest of being able to say that I "tried everything", I created a png file that was nothing but a transparent background, as well as one that was nothing but a white background. Rendering text on the transparent file looked just like it did as if I had created the whole thing in memory - in other words, crap. The white png file resulted in perfectly anti-aliased text.
I just don't understand...
EDIT ===========
I also created a new white image that had the transparent color set to white. This generated a better image, but not NEARLY as good as having some sort of color on the bitmap.

I tried it both ways - neither result was acceptable, but the transparent color version was the best of the two.

Hello everyone.
I'm developing an aplication and in one part of the code i want to change the state of the Visible label property.
EX: By default
label.Visible = false and then, somewhere in the code i make
label.Visible = true .
When i run the aplication everything goes right but, in debug mode, after changing the property state from false to true if i check the value in the immediate window it still appear false.
What's the problem.
Excuse my inglish but it is not my native language.
regards Jonatan. Thanks.

Weird - I tried to recreate this problem in VS2010 but could not do so.
Which version of VS (and framework) are you using?
|
|

|

Hello. Thanks for the reply.
I'm using VS2005 and the framework is 2.0.
regards jonatan

The property has a setter and a getter. The "getter" only shows the current value.
Now, when you change the value in the debugger, the application that is being debugged is halted - you can see how the application even pauses drawing the screen if it has hit a breakpoint.
Once it continues, then it will send a message to the label, saying it needs to change visibility. The application that's being debugged will do so when it's processing this message. That takes time - in the meanwhile you're looking at an old value in the debugger.

hi
I created a global class that contains this code:
public class ClassS
{
#region variable et propriété
private int codemessage;
public int Codemessage
{
get { return codemessage; }
set { codemessage = value; }
}
#endregion
I would like to create a subclass that inherits this property, stating in this class values of this property, the code message can have 13 values of 200 to 212, and should be declared in this class,
for example:
200=immatricule
201=kilometrage
...............

Ok, so derive from it. The property is public so it will be available.

Then you need to use a collection
And "class c#" as a subject title in the C# forum is pretty much useless and uninformative. Try something more descriptive of your question or issue next time.

yes you are right, and thank you for the comment
but in the child class property is not displayed and here is the code used:
namespace CarteGrise
{
public class CarteGrise :ClassS
{
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ClasseSup
#region variable et propriete
..................
#endregion
public List<ClassS> liste = new List<ClassS>();
|
|
|
|
|
If I understand this, then CarteGrise does not need to derive from ClassS at all. Also, if ClassS only contains one property then a class is overkill and unnecessary. A simple collection of stings would be sufficient.
