Because he doesn't ask about feature of the C#, only about a feature of the Windows Forms. If he knew how to do it in Visual Basic, but had a problem translating it to C#, it would be a good place to ask, but he asks (not sure how to do it, so I'm guessing here) for a method or property, that manages apearance of Windows Forms control.
Following your thinking, CodeProject forum should be truncated to C#, Visual Basic, C++, PHP, ... (hope you see the pattern here). And when someone has a problem with Windows Forms or ASP.NET, he has to search in all languages instead of just searching forum more specific to his needs.
That's why I think, this question should go to Windows Forms, not C#.

i want that my prefix or my first 4 char value in my textbox which is "SPR-" cannot be deleted or modify by the user...how to code that.. plz.
|
|
|
|

One would assume that you are going to do “something” with the contents of the TextBox after the user has finished entering data into it; in which case, if the data does not have an “SPR-“ prefix, add it after the fact.
|
|
|
|
|
Use a MaskedTextBox[^] instead, and set the mask to "SPR-&&&&&&&&&&&" where the number of '&' characters equals the max length of the input.
You can remove the underscore by setting the PromptChar property to space.

This is my stored procedure part to find the count of a column specified.But here i m getting a conversion error

Hello,
I was wondering whats the proper way to name your global variables.
I use Visual Studio 2010, and I use two add-ons: ReSharper and Stylecop, to learn how make better code.
However, their advises are conflicting.
For example, if I'd have this code:
public class Example
{
private static object _staticExample;
private const object CONSTEXAMPLE = null;
private object normalExamle;
public void main()
{
this.normalExamle = "";
normalExamle = "";
}
}
(1): How am I suppose to call this? ReShaper tells me it should be _lowerCamelCase, however Stylecop tells me to not start with an underscore[^]
(2): What about all capital constants? I see them all the time. However ReShaper tells me it should be UpperCamelCase. Stylecop does not care about casing or it being full capital, only that the first letter is a capital.[^]
(3): How am I suppose to use the variable? Stylecop says I'm suppose to use this. (3.1)[^] However, when I do that ReShaper says this. is redundant, and that I should remove it (3.2).
Whats the right way to do this?
Thanks

I use what the Framework uses, "Pascal case"
DataTable , DataSet , BackColor , StreamReader
As it's the de-facto best practice.
However, so long as the code in your company is consistently using their style,
Then you're much better off getting used to it.
If every developer has their own standard, then there's no standard at all.
please have a look here

Different tools have different rules, some even allow you to change these.
Personally I agree with "_" rule on point 1 (as does Microsoft I *think*, it definately did at one point, but there is a glimmer of a memory that they may have changed their collective mind).
Capitalised Constants are probably a hangover from either Java or c++, we used to use CONST_EXAMPLE in c++. Microsoft suggests you use the CamelCase for these.(or I might have set up a rule in FxCop to do this).
Personally I use FXCop for this, work as it is the MS tool to do this.

That's not global; it's private.
I don't use underscores, and I use lowercase for private members.
I suspect that the UPPERCASE habit is from C #defines.

Hi guys.
I wanna know if I add a windows.forms reference in my web project and use
System.Windows.Forms.SystemInformation.PrimaryMonitorSize
its a good thing.
or javascript window.screen.width its more recommended to web projects?
|
|
|
|
|
Managed code will run on the server, not the client; and it is likely to fail, as there is no user logged in, hence no primary monitor is known.

oh right!! 
thanks dude

hi all
is there any 64bit hashing algorithm implemented in .net?
i am using .net 3.5 and need to encrypt a string with length of 3 to a byte array of length 8 or 10
for example :
hash("ABC")="!@?{%ER)@w"
any suggestion?
|
|
|
|
|
Take the first half of the MD5 hash. I don't know how many collisions it will create or if they are uniform but it may work?
|
|
|
|
|
hi
no i need a class implemented in .net some thing like MD5 Class .
but it have to generate byte array of length 6 to 10 (not 16 byte or higher).
|
|
|
|
|
I would read my post again. Last time I checked 16/2 = 8.
|
|
|
|
|
it would give ambiguous meaning
does anyone know something about this problem?
|
|
|
|
|
All hashing algorithms give ambiguous results. The number of expected collisions is directly proportional to the input size, output size and quality of the hashing algorithm. Read the Wiki page on the subject for more information about hashing.

Hi every body,
I’m working with the Crystal report in C# application, and using Linq to connect database in SQL server.
I need to create Crystal Report whose datasource not only one table but two and these two tables are related to each other with a foreign key, so I tried to join them then give the result to the report as a datasource but in the result I have repetition in data, I mean each row from the first table goes with all the rows from the other table so when there must be just 3 rows as a result I have 9 rows
can any body help?

This means that you don't have a real join in place. Basically, you are seeing a case where you are getting a many to many result back - your query should limit the results.

Thank you Mr.Pete O'Hanlon for your reply,
But what you have said is right and I guessed that, then I made sure that the returned rows from the query were without repitition ( I stopped the program while debugging and see the values)
I think that the problem might be when selecting the database fields for the report !!
What do you think and how to solve it ?
Thanks to be helpful

I suspect the reason why you're getting the results you are is because of the JOIN type that has been used in the SQL query. You'll have to craft the SQL statement to return your proper results yourself. You may want to read up on the different join types [^] to understand how they work before proceding.

Either You not using internal link in data sources at crystal report end or you not use grouping option for that
