• Visual Studio Express Editions How I get the activation key ???

  I successfully created 4 myself a .net account(clicked "Register now!" in Product Activation dialog, filled some fields and gave my e-mail address, received two mail, followed the confirm link etc.) but I  found nothing about the location of the activation key. Help me please! When you received the e-mail verification mail, the link you followed to verify your e-mail would have taken you back into the system and the page displayed would provide you the activation key.  Since you have verified your e-mail, you should be able to go through the process again and go straight to the activation page ...Show All

• .NET Development System.IO Q's

  Hi there. I am doing some mobile dev in C#. I know that the .NET Framework is stripped down, becoming .NET CF for mobile devices. Is there a way to retrieve the startup path of the application thanks! That is correct I do get that error message. however I was able to sort it out!   I had to import System.Reflection and use:   Assembly.GetExecutingAssembly().GetName().CodeBase.Substring(0, Assembly.GetExecutingAssembly().GetName().CodeBase.LastIndexOf("\\")) That gave me the startup path and works great! Bad thing about it is that if your run the mobile app on the PC.. it throws a JIT error... but thats fine I guess beca ...Show All

• .NET Development ADO and Role Base

  Hello, I have this question: We know that Enterprise Services (ES) offers secure model i.e. Role Based Security (at a cost of  added comlexity) But can one achieve this purely using ADO.NET based model If no, how can I simulate the Role Based Security if we dont want to go the ES route Thanks Thank you SvenC, that was very helpful. I am well aware of the difference between ES amd ADO. The short answer from what you said is the ADO.NET namespace is not shipped with role-security. I guess to achieve similar functionality, i will either have to implement is in-code or rely on the DB/windows groups. Thanks ...Show All

• Windows Forms Form HasChanges properties.

  I wonder is there a easy way to check if a form has been modifed What I want to do is when user click the close button, check if there is any changes in all the textbox and confirm they don't want to save. I know I can go to each control and add a textchanged event, but I got more than 40 controls. So it is a pain to do this one by one. Thanks. Hi Terence, I am not aware if there is such a property or event. What you can do is possibly iterate through all the controls on the form using a loop as shown below: (assume that allValidated is a boolean variable which will be used like a flag. Outside the loop, check for allVali ...Show All

• Visual Studio Express Editions I do not want SP2. I do not want SP2.

  Hi. I run on Windows XP Professional SP1 and I really need Visual Basic .NET Express edition, as SharpDevelop2 is very buggy (atm). The thing is: I do not want SP2. Please do not flood me with comments such as "BUT OMFG SP2 PWNZZZ SP1 ! !" but tell me one good reason why to update into it. Not "security", not "more stable", but something real.

• SQL Server Size of PDF reports

  Guys, The same of the reports with charts are really around greater than 1mb. I have one report that is above 7mb. Is it really that high for reports with charts That seems a lot. Is there anyway I can shrink the size of the PDFs Thanks, Enkh. You can not control the rendering extensions but you can install a new one. I think that out there are some third party extensions that render to DOC and different extensions that renders to PDF, you only have to find out which compresses better your rendered documents. ...Show All
