How do i charge credit cards for like a resturant program?
|
|
|
|
|
|
you need to create a vendor account with service provider like Verisign. they will provide you few APIs using which you will be able to charge customers through creditcard.
It is recomended that you use SSL for communication and do not store credit card details. If you are really interested in saving details, do encrypt before you save.

What is serialization, how it works in .NET?
|
|
|
|
|
|
Serialization is used to save the state of the object. You can save the state, i.e. can serialize to XML format or to Binary format.
In case of Binary format you can deserialize and invoke the methods. In case of XML deserilization, you will be able to access only public properties.
hope this information helps you...

Hi,
I am writing a networking application in C#.
The application transfer data of a few MegaBytes.
Initially, the application takes up about 10MB,
then after the network data transfer for about 6MB,
the memory usage (info from the taskManager) is about
100-200MB !!! So what is the reason for the application take
up so many memory ? And how can I solve the problem. It seems
that .Net application is a big memory eater !
Thanks

There can be all sorts of reasons for memory usage. The main one is, if you create a variable that impliments IDisposable, you should use a using block to ensure the memory is cleaned up right away.

Try to use a reasonable buffer when transfering data from your file to the network. It's simpler to just read the whole file into a single array and then write it out, even though that is probably the worst for memory use. Just because memory is managed, doesn't mean it takes up less space.
Also, in windows memory is assigned different uses. Most of the memory you are seeing will probably be released if other applications need the memory. You can usually see this effect if you minimize a .net forms application.

If you create many large objects, they will stay in memory until they are garbage collected even though you have dropped the reference to them.
These might apply:
If you are using a buffer, try to reuse it instead of creating a new buffer for each data block.
If you are concatenating strings, use a stringbuilder instead of the += operator of the string class. Strings are immutable, so eventhough the += operator gives the impression that the string is just appended with the new data, a completely new string is created and the data from the two strings are copied into it.

Hi,
I am writing an client-server application with networking in c#.
For the client part, I am using a synchronous network connection, that is,
when the client request the server, all the client features will be
hanged until the server response. So is it a common strategy in
implement client ? I am considering using threading or asynchronous
network connection, but it seem too complex and hard to maintain
the user logic. So any other good methodology to handle the problem ?
Thanks

For example,I draw a line on the surface of graphics with GraphicsPath.
Sometime I want to clear the line,how should I do?
|
|
|
|
|
If you want to clear the entire entire canvas, just call your Graphics object's .Clear() method.
If you want to clear just the line itself, you'll have to create a new pen the same color as the canvas background, then use it to redraw the line exactly the same way it was drawn originally. If your line intersects with other lines or graphics objects, it'll draw a background colored loine through them.
The only other way to do this would be to redraw everything onto the canvas that was originally drawn, but don't draw the line that you want to erase.

I have a web application that needs to modify some files in the web folder. I have notice that after installation, the ASP.Net account doesn't have modidy permission and have to grant it manually. Is there a way for me to grant the ASP.Net account modify permission during installation throught programming or setting so properties? Thanks.

It's not a good idea to modify the permissions on the site's parent folder. A better idea would be to create a subfolder off the site root and put your modifiable files in there.

I have set the launch condition in my installer to check for the .Net Framework. Is there a way for me to run the dotnetfx.exe if the condition fails. I want to run it automatically or programmatically from the installer. I can launch an executable programmatically, but where do I place the code for it? I perfer to do it automatically though.Thanks.

I believe you can get a merge module from Microsoft, which means your installer will install the .NET framework for you. Personally, I write a little exe to run my MSI and anything else I want to run.

Where on the MS website can I find the merge module? I have typed in different combination of the words merge module, .net framework, and dotnetfx.exe, but can't find anything relevant. After I have the merge module, do I just added it to my installer project? Thanks.
