Yeah just like Pete said.
But sooner or later the day will came when you'll need to modify almost everything at least in a module
if not all. Situations like:
Up till now you(not you personally, the company/people) moved a product from an area to another eg from production to warehouse for example.
Then they decide that they want a more detailed transaction so instead of moving from production to warehouse you will
have to move them from the production line to the warehouse. Or the other way around meaning that management decided that they don't need such detailed transactions. Such modifications are bound to affect many reports/modules.
So the best thing you could do is make it pluginable(sorry if the word doesn't exist) and try to design the app/modules
with such modifications in mind. Even then someday you(the team) will have to modify large bits of code.
After all an ERP system is meant to accommodate the businesses of a particular company/plant.
If/when that changes you'll have to change it too.
I've done something like this a little while ago. Fortunately I was familiar with the business process and I
anticipated some of the possible changes. But not all of them.
Best of luck.
All the best,
Dan

I am gratefull to you Dan for a very good piece of advice. It's very handy to have suggestions from the ones who have already done the work on ERP.
Thank you so much.

You're welcome.
Oh, and it's not that hard really. Just a lot of work(huge if just one person) and most importantly carefully design of the businesses process.
If you're not familiar with it, I suggest you take some time to familiarize yourself with it and then start
designing/developing the app.
All the best,
Dan

Although I am developing all these as individual projects but the thing which is worrying me is how to join all these in a way that incase of adding another system I dont have to change the code for my project. I just create another project compile it and just plug into the system
This is would be a large project even for a relatively small company.
The larger the company the more complexity involved in the integration. A simple example is a company might want to manage contractors as personal (human resources) while paying them as a project expense rather than a payroll expense.
An inexperienced developer is unlikely to get the functionality of the individual components correct much less correctly architecting/designing the cross project needs correctly. As an example of this corrrectly implementing point of sale taxes for a retail company is a very complicated task.
Not to mention of course that any cross project needs are directly dependent on the business needs of the company itself. Thus the first step is to learn the needs of the company.

Hi,
How can i insert a button inside a textbox in the same column in datagridview control.
|
|
|
|
|
I think for accomplishing Button inside Textbox this previous thread in same forum HERE[^] might help you.
After then there's not hard to make it involved in datagridview.
I hope you want button inside textbox. NOT button with a textbox in same column.
|
|
|
|
|
thanks Hiren ,
i want a cell in datagridview that contain a button inside a textbox,when i press the button i get some value and i put it in textbox.
if there is a solution plz send it to me.
Regards,
|
|

|

That will take a lot time of yours 'cause you need to make custom control or need to use third party control for that, And it's time consuming and task of R&D.
If design doesn't matter at all then you can achieve same thing using TextBox with Button outside, Your cell can contain multiple control there's not any restriction to only one.
|
|
|
|
|
no,I'm obligated with that design,thanks anyway.

When I google the topic I got many suggestions like this one: http://blogger.nilanka.net/2010/08/split-web-application-into-multiple.html
Is this the only way to do it? We have a big Web application project (ASP.NET 3.5) and we use VS2008. Does VS2010 have any support for splitting a web app into multiple projects or do we have to do this workaround?

You'll have to split it yourself; Visual Studio cannot "guess" what pages make up a (child) project.

Ok, then I'll give it a try!

in my application i try to identify if the sql express server is running in a remote pc, before starting my local service.
i use servicecontroller class and it gives the status as running, but through my service when i'm trying to access the DB in that sql server it returns the DB is not there, i used a thread sleep and then tried , it worked well then.
so seems to be there is a problem with sql service status and the real starting , is there any solution i can do instead of thread sleep.

I doubt ServiceController is a good idea.
Some reasons why it isn't a good idea.
- In a standard data center set up box A is not going to have permission to access the database box.
- Detecting that the service is running doesn't diagnose all possible failures.
The simple solution is to just do a do nothing query like the following
select 1
A better one might be to verify that at least one of your tables exists, but still a do nothing query like the following.
select 1 from mytable where 1=0

thanx... If the sevicecontroller is not a good solution is there any other class that i can use instead of it.
thanx in advance.

That doesn't make sense.
If you need to insure that a remote service is up AND you have permissions to access services then you would use ServiceController.
Expanding on what I already said.
- In a standard data center set up you will not have those permissions.
- Normally in any client server (database) set up it is outside the problem domain of the application to verify that the database service is running. It doesn't matter if the service is running. What matters is if the database is accessible.
- Not all failure scenarios can be verified using ServiceController. You could very well find that the service is in fact up but be unable to connect because your app has permissions to access the service but doesn't have permission to connect.

Visual Studio 2005, using SQL Express, I have stored SQL procedure to insert a row into my database. The return code from ExecuteNonQuery is 1 indicating a row was added, but when I check my database, there is no new row. When I run the procedure from the IDE, it inserts a row.
When debugging I do get Method may only be called on a type for which Type.Is Generic is true.
Here is the code block
using (SqlConnection conn = new SqlConnection( sqlConnection1.ConnectionString))
using (SqlCommand cmd = new SqlCommand("dbo.insertIntoCustomerTable"))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@companyName", ""));
cmd.Parameters.Add(new SqlParameter("@unitSection", ""));
cmd.Parameters.Add(new SqlParameter("@streetAddress", ""));
cmd.Parameters.Add(new SqlParameter("@city", ""));
cmd.Parameters.Add(new SqlParameter("@zip", ""));
cmd.Parameters.Add(new SqlParameter("@buissnessContactName", ""));
cmd.Parameters.Add(new SqlParameter("@buissnessContactPhone", ""));
cmd.Parameters.Add(new SqlParameter("@buissnessContactEmail", ""));
cmd.Parameters.Add(new SqlParameter("@buisnessContactEmailBad",false));
cmd.Parameters.Add(new SqlParameter("@groupEmail", false));
cmd.Parameters.Add(new SqlParameter("@isbAnaylist", ""));
cmd.Parameters.Add(new SqlParameter("@requestorCode", ""));
cmd.Parameters.Add(new SqlParameter("@toCustomer", false));
cmd.Parameters.Add(new SqlParameter("@toCustomerDate", ""));
cmd.Parameters.Add(new SqlParameter("@fromCustomer", false));
cmd.Parameters.Add(new SqlParameter("@fromCustomerDate", ""));
cmd.Parameters.Add(new SqlParameter("@toPST", false));
cmd.Parameters.Add(new SqlParameter("@toPSTDate", ""));
cmd.Parameters.Add(new SqlParameter("@iacUpdated", false));
cmd.Parameters.Add(new SqlParameter("@sft", false));
cmd.Parameters.Add(new SqlParameter("@vpn", false));
cmd.Parameters.Add(new SqlParameter("@epnVendor", ""));
cmd.Parameters.Add(new SqlParameter("@epnPackage", false));
cmd.Parameters.Add(new SqlParameter("@dlInquiry", false));
cmd.Parameters.Add(new SqlParameter("@abstractUpdate",false));
cmd.Parameters.Add(new SqlParameter("@juryExtract", false));
cmd.Parameters.Add(new SqlParameter("@bulkExtract", false));
conn.Open();
cmd.Connection = conn;
int rows = cmd.ExecuteNonQuery();
MessageBox.Show("" + rows);
cmd.Connection.Close();
}

do you by any chance have two databases, one you are looking at, and then being copied when launching your app (and being updated as expected)? Seems like having Visual Studio add a database to a project creates such a trap...
|
|
|
|
|
I double checked and the connection is to the SQL express database, so that does not appear to be the problem, my guess is I don't know how to insert a nullable field for the date fields and or the boolean fields.
|
|
|
|
|
IMO that does not match with your earlier statement.
However, if null is your problem, probably this[^] holds the solution.
|
|
|
|
|
Luc, I don't know if it is my problem or not.
|
|
|
|
|
Then stop making arbitrary statements, perform one or a few simple experiments (a table with one or two fields), and gather some facts.

Hi, I have a dll written by C++ with a function:
extern "C" long __declspec(dllexport) __stdcall Record(BSTR *buf, int *h);
Now, I want to call this function from C#. The problem is that I don't know how to pass unmanaged type (BSTR*). I try to marshal with UnmanagedType.BStr, but it's BSTR, not pointer to BSTR.
|
|
|
|
|
if you mean your native function is taking an input string pointer and may also replace it by a pointer to another string, I think you're in trouble as far as P/Invoke goes: who is going to delete the managed string that you no longer use, and how is the new native string going to get adopted by the managed world??
I would go for a simpler API, assuming the API can be changed that is.
|
|
|
|
|
Since BSTR is a pointer itself, I guess that passing BSTR* means that you have to pass an array of BSTR's. I am not sure if this would work, but these are my ideas:
You might allocate each BSTR of the array with the function SysAllocString. Yes, it returns a BSTR, but like BSTR is a pointer, you can import this function setting IntPtr as its return value, so you would build an array of IntPtr.
When you import the Record function, the first parameter should be of type IntPtr. So, when you invoke the Record function you should pass the address of the IntPtr[] array. You can get it with Marshal.UnsafeAddrOfPinnedArrayElement method. The second parameter is easy, I guess it is the length of the array of BSTR strings.
