Actually, that's not true. When you drop an instance of your control on a form, the code IS executed.

If your talking about your controls position on the form, AFAIK, you can't do that in the constructor. I don't think your control has it's Location property set until after the constructor returns.
I could be wrong though...

im a total newbie to c#, visual studio .net 2003 and even Access database 2000.. im doing my forms using visual studio and my data are all stored in access db..
i've some vague concepts abt how to design my app.. im not sure it'll work as i do not have enough knowledge yet, and i doubt i'll have enough time to research and come out with a solution on my own..
and so im here now, need some guidance, hopefully it's explained very simply to me as i really have some difficulty understanding those acronyms/terms for an app...
im doing this> a user keys in an ID no. in a textbox and then hits the enter key/Go button in a main form in visual studio, and the app will retrieve selected data (that ID no. user's data) out of Access tables and display that data in another form within Visual studio..
i hope to use wizards as far as possible due to simplicity and time constrain.. i understand that i cant get the wizards to meet all my criterias/expectations/aims so if need be, im ok to not use a wizard and build from scratch.. but that's where i get seriously stuck, i donno how to use visual studio TOGETHER with Access db.. i already read tutorials and help books but they are meant to teach a user to create forms and queries all WITHIN Access itself.. i wont be doing any forms within Access; im only doing forms in Visual studio and keeping data in Access.. i read microsoft access help but it's not basic enough for me to understand.. i need a simpler or more idiot teaching method but i cant find it online.. any recommendations? to be emphasized again> im really short of time.. so i cant read up too long either.. i cant understand as quickly without truly doing and exploring the work process... so in a dilemma now, whether to read and learn or doing by trial and error..
some things i have to do:
1) how can i retrieve selected data (that is, retrieving just the data of user with that particular ID no.) from access db to display in my form?
2) i've a form for employer to fill in.. this is to create files for customers who do not have a file stored in the db yet.. how can i save/store all the data that has been filled in into access db and at the same time ensure that the data is stored under a particular ID no.? (among the info filled in, one of the fields entered is ID no. so i want to keep all these data under THIS ID no. that's entered in the form)
3) does anyone know anything about nevron chart, .net charting or microsoft chart control 6.0? i would like to use the data (date and time of transaction) from db and display these data in a graphical manner, that is, to display data from db in a bar chart which is within visual studio.. which chart software can be supported/can be run along with access db and visual studio .net... which chart software is more appropriate for my needs?
please help me! i've tried on my own already but i cant do... i really appreciate your understanding!
thank you very much!

Hello,
I have in the declaration:
private Control[] allocGrading;
Then in one of my methods I have a call to another method in which I am passing the ControlArray:
this.SetupStageAllocation(this.allocGrading);
.....
private void SetupStageAllocation (Control[] controlArray)<br />
{<br />
<br />
controlArray = new Control[numStages];<br />
}<br />
However, my declaration of allocGrading still remains null, and I want to pass the value of Control array to SetupStageAllocation by reference, because all the Control[] will be setup in the same way. Any ideas what I am missing?
Thank you
|

|

you need to declare your method to take array by ref
private void SetupStageAllocation (ref Control[] controlArray)
{
controlArray = new Control[numStages];
// Do some stuff
}
this.SetupStageAllocation(ref this.allocGrading);
|
|
|
|
|
Thanks a lot, but I already figure that one out.
|
|
|
|
|
If the method always creates a new array, it's better to make the method return the array instead:
this.allocGrading = this.SetupStageAllocation();
private Control[] SetupStageAllocation() {
Control[] controlArray;
controlArray = new Control[numStages];
return controlArray;
}

I agree with Guffa. If you start getting used to passing by reference all over the place, it will soon get out of hand.

Hi
Im trying to find information about how to implement a massemailer. I've got a site that needs to be able to send out alot of emails (not spam). My current solution works for 400 recipients but more than that it starts to freak out. Been thinking of splitting the recipients into various groups and have threads sending them out, but I really doesnt know where to start here.
Do you guys/girls out there have any information on where to find a tutorial or something similiar regarding this kind of email stuff? Buying is also an option if the product is fairly cheap and good.

Hi,
I get error
"Couldn't get process information from remote machine" when i try to run Process.GetProcesses().I understand that this is because i dont have administration rights.How can i solve this problem.Is there a way where in i can give some permissions to the user to execute that part of code alone.
Hope to get replies soon.
Thanks

I don't think so. You could try building that functionality into a seperate program, then launch that program with Administrative permissions (provided either you know an admin's name & pass, or the user fills it in for you).

I guess i havent explained the case properly.
I have a program where i try to get the processes running in the machine through GetProcesses().I connect to a remote machine using a user who doesnt have admin rights.When i run the program from the remote machine i get error saying "Couldn't get process information from remote machine" additional info :"Access is denied". I cannot give admin rights to this user but i stil want the program to return me the processes through GetProcesses().Is there a way to give access permission through the code , such that i get the processes even though the user does not have admin rights.
thanks

Menu Item names are directly coming from the database and i want to attach menu item with the event handler names.
so i name event handler as "handle" + item.name(value from database) + "click".I want to attach it dynamically.
the code is as follows
//sample code
public class myclass
{
protected void Handle_FileMenuItem_Click(System.Object sender, System.EventArgs e)
{
}
public bindeventhandler()
{
string dynamiceventhandler="";
dynamiceventhandler="Handle_" + item.Name + "_Click";
Delegate temp=Delegate.CreateDelegate(typeof(EventHandler),this,dynamiceventhandler);
item.Click+=(EventHandler)temp;
}
}
The code is throwing error. Error binding to target method.
Can anyone pl explain how to solve this error...
i got the idea from this url

Hi,
I tried your provided code and it works just fine. Did you verified that the value of item.Name is e.g. FileMenuItem?
Do you have a target method for all items that wil be binded ?

The IIS control - you can find it under the "Administrative Tools" of the PC / server where the IIS is hosted....

Hello, I'm trying to access a DataTable from a Typed Dataset through Remoting but when I call my method it throws the follow exception:
[SerializationException] The constructor to deserialize an object of type
TBPerfilDataTable was not found.
But, when I try to return the full filled typed dataset it works... It only doesn't works with DataTables.
Any idea?

Hi Wender,
I'm not really sure if the TBPerfilDataTable class needs to have a default constructor (without any parameters). If I access an object using serialization (e.g. by using a WebSerice), the serialized class always needs a constructor without parameters.
Is your datatable marked as serializable ?

Sebastian, thanks for your attention
First it throws an exception about Serializable Attribute not found, so, I marked all my datatable classes as [Serializable()]. Then, I tried again and got that exception. I tried to reimplement ISerializable interface but I didn't understande how to do this.

If you are deriving from the DataTable class, then you must add the following code
protected MyDataTable(SerializationInfo info, StreamingContext context):base(info, context)
{
}
