Delphi 7.0 to .net migration

SAMRAJ — Wed, 09 Dec 2009 10:27:23 +0000

Hi,

Can anyone tell me which is the best language feasible to migrate from Delphi 7.0 and what are its advanatges and disadvantages.

In our delphi application we have a framework where the other applications inherit the forms designed in the framework and add their own additional components on it.Is it possible in .net.

Can the code now present in Delphi be reused in .net?

Can anyone tell me something about the .net version for Delphi?

Using TRichEdit: What color is this line?

Sandisk — Sat, 27 Jun 2009 18:31:46 +0000

I am using Delphi 7 and a TRichEdit component that has various colored lines in it. For example, text on lines 1 through 10 is clRed, lines 11 through 14 are clGreen, lines 15 through 25 are clRed, lines 26 through 27 are clGreen, etc…

What I would like to do is generate events that would displaying only clRed lines, or only clGreen lines. IOW, on a TRadioButton.OnClick event I would like all the clGreen text to disappear. I figure that I will have to play an optical trick on the user, using two TRichEdit components: one containing the original multi-color text, and a second component that shows the text with the clGreen text missing. By turning off/on the TRichEdit.Visible property I can acocmplish this trick, however, I still need to know how to pull/scrape/copy all of the green text from the one TRichEdit to the second one.

Thanks.

Access violation in dcc70.dll

Hi,

I’m trying to run a delphi (V 7.0) application and as I hit the run button I’m getting an ‘Access violation at address 00ACF337 in module dcc70.dll. Read of address 000000C4′ error message. I used a dcc70.dll repair tool and the problem was not solved. Any idea of how to fix this problem?
Any help would be much appreciated.

Thanks,

Populating one combobox in Delphi 7 from another?

RavenMoon — Fri, 27 Mar 2009 14:55:49 +0000

I have one combobox in which you select an option. What is the sql used in the query to restrict the second combobox depending on the first value. All I seem able to get is:

[SELECT Name_Of_Race FROM Races WHERE
Name_Of_Allegiance = DBLookupComboBox1.Value]

Here, when I press the button to set the first combobox as the selected value, the second one appears but with no values in it. I have replaced DBLookupCombobox1.Value with a correct value and the second combobox behaved as expected, so I can only presume I am using an incorrect identifier. If anyone could help it would be much appreciated. Thanks !
