Aren't you going to compensate him for all the univotes he got on that question?  .

this is all you need to not show the data:
public void button1_Click(object sender, EventArgs e) {
MessageBox.Show("Nothing to see here, moving on");
}

can't believe I'm about to use these words but... Google. Search feature on CP.. there are a number of options you can take besides "gimme code" for a unclear problem. a little advice from a newbie that I've learned
#1 break your problem down into bits. not one huge line of garbled question about a project we have no clue what you are doing.. Break it down into individual parts.
#2 figure out how to do each part separately.
#3 if at that point you still do not know how to make a specific part work.. Show some of your attempts,, Explain what you have tried, what errors you get,,, and for crying out loud state your problem CLEARLY and CONCISELY. Then the real programmers haunting these boards will be more than happy to help you a little bit. What they are NOT happy doing is doing the entire freakin project for you. Especially when nobody but you is even sure what the project is.
Programming is a race between programmers trying to build bigger and better idiot proof programs, and the universe trying to build bigger and better idiots, so far... the universe is winning.

It would be better if you tell us what is kind of a database it is and if you don't want to show it on data grid view, then where do you want it to be displayed?
|
|
|
|
|
first, the question is not well formed (ok, my english too)
second, what i read and understand: he dont like to use the datagridview "because it cannot display images".
i understand from this, that he found some piece of code in the internet, used it, but the sample uses a datagridview and databinding. and now he would like to change the sample program to search for a value, and fetch the values from the db to controls on the form, and he has absolutly no clue where to start (if this is homework, the question arise: why does he not know where to start? not listening? no teaching?).
beside the fact, that a datagridview definitly can be abused and [B][U]can[/U][/B] display ownerdrawn cells (=everthing is possible, images too), he can react on the click event of the datagrid and display the image in an additional control on his form.
all this assuming w´re talking about a windows form app. wpf would open other possibilities.
I cannot remember: What did I before google?

I second your thoughts Thomas. He does not even seem to be interested in replying our feeds.

Hi,
For your need follow these steps.
1.create a connection with your database
2.create an sql command to fetch the values from your database
3.next, fill the values in a datatable
4.and then bind those values to your grid

Hi..
I am developing an application in which I am sending a data packet using UDP 9050 port.When I run it disabling wifi, it works fine.But when I run it on a laptop with enabling wifi ON, It doesn't work.
Please guide me.

It's possible that you are hitting a port conflict with another application, or that the firewall is not allowing the application to pass through this port. To see if you're getting a conflict, try running netstat -a from the command prompt.

you may be binding to the wrong adapter... to see if this is the problem, change the order of the adapters:
To view order of adapters: on cmd prompt type: ipconfig (the result will be the default bind order)
To change order of adapters: last adapter enabled will become last in the list (so change the order by disabling/enabling in the network connections menu accordingly)
if you determine that this is the problem, then you have to manage your adapter binding a bit smarter in the code.

Hi,
I'm trying to create a memory mapped file file using
var mmf = MemoryMappedFile.CreateFromFile(@"C:\Temp\XMLFile.xml", FileMode.Open, "memMapFile");
in the OnStart() of the service class. The mmf gets created, but trying to access it from an application using
var mmf = MemoryMappedFile.OpenExisting("memMapFile");
leads to a FileNotFoundException.
When the file is created in an application instead in a service, this works.
What am I missing?
Thanks for your help!

You need to create an inter-process memory map file with MemoryMappedFile.CreateNew method. In this way you'll be able to access it from different processes.
|
|
|
|
|
Not if he's only accessing it from the Service, not from other processes.
|
|
|
|
|
Thanks for your reply Ciumac!
I went trough the description of the MemoryMappedFile class, but couldn't figure why MemoryMappedFile.CreateFromFile should deliver a result different than MemoryMappedFile.CreateNew. Nevertheless I tried it out - no success!
|
|
|
|
|
Is it a local variable in the method? Or a member of the class?
|
|
|
|
|
Thanks PIEBALDconsult!
It was a local variable.
Best regards!

Hi guys, I have the following problem.
I have 3 buttons (ProcessA, ProcessB and ProcessC) and this are the scenarios:
- By the time I push ProcessA, then disable ProcessB and ProcessC buttons
- By the time I push ProcessB, then disable ProcessC and ProcessA buttons
What I am doing now to set one button properties from an external thead are the following sentences:
if ProcessA is started, then
changeBtnStatus(btnProcessB, false);
changeBtnStatus(btnProcessC, false);
if ProcessA is stopped, then
changeBtnStatus(btnProcessB, true);
changeBtnStatus(btnProcessC, true);
and the same for processB
if ProcessB is started, then
changeBtnStatus(btnProcessC, false);
changeBtnStatus(btnProcessA, false);
if ProcessB is stopped, then
changeBtnStatus(btnProcessC, true);
changeBtnStatus(btnProcessA, true);
this is the generic method
public void changeBtnStatus(Button button, bool status)
{
button.Invoke((MethodInvoker)delegate { button.Enabled = status; });
}
ProcessB is working fine, but ProcessA button is not working well. The ProcessC button is not getting disabled by pression btnProcessA, why this happens? I have made some tests and I realized that I uncomment ProcessB block of code, ProcessA will work correctly. The problem resides in chaging btnProcessC propierties because both blocks set this property.
Hope this is enough information.
Thank you in advance!

your message isn't very clear and this isn't C# code; you probably have a minor mistake somewhere, with what you have shown and told us, I can't tell you in any detail.

Hello,
This is the situation I have an assembly A (plugin) loaded into separate app domain, that assembly fires a couple of events.
And i have a class B created using the default App domain.
Now Class A raises and event and event handler in class B catches that event, but since it is called from another App domain (A) it cannot see variables of app domain B (all variables are null) in this case a public static object that is 100% not null on app domain B.
I think i understand why the variable is null, but how do i execute event handler code in app domain B so that code executed in app domain B will see the variables initialized?
I have tried CrossAppDomainDelegate but it can only call mehods that don't have any parameters, and since this is an event handler it has parameters and not standard event signature but with a custom EventArgs.
How can i solve this problem.
Thank you!
