A picture box is often mistaken for a high end control. It's there for people who are incapable of writing some basic drawing code. I'd create my own control, have it draw the image in it's paint event, then it's trivial to have it draw the image to the bounds of the control, and not hard to make it draw as big as it can with the correct aspect ratio.

Hi
I have build an application which needs to write log files in user specified folder during settings with in the application + it need to connect with Access and update the records. When my application runs on XP it works fine but when It runs on Vista it do not get the default credentials and used to have readonly rights on the machine.So write log fails and while updating access it does not allow me.
I can check the default rights using system.security.principle class but how can set the default credentials for application as the user who run's the application do have rights to read/write/delete on machine.
Any idea's
Best Regards

Hi, Im doing a conversion to an old calculation program at work. It has 1000+ input variables, which I have grouped in 15 or so classes, which I declare arrays of to simulate a database. Then I have a function that reads or writes these to disc.
The passing of the array seems to change the array to a system.array[] instead of the original <whateverclass>[]
Declaration
Private Function ReadDataClassAllFieldsToDisk(ByRef CheckObject() As Object) As Boolean
Called with
ReadDataClassAllFieldsToDisk(Hissdata_Arr)
So, Question 1: Why does the CheckObject I get in the function throw an error when I finish with the function saying that the objects are not of the same type?
Question 2: Can i automatically add a new object of the same type as the otherones in the array? (know I have a select thingy to check the type and make a new instance and add to the array?)
Thanks for just reading this, I hope anyone can help?

Hi Jocke,
Supposing that you are using vb.net, and not knowing the rest of the code in the function, the error might not point to the objects in your array.
Generally speaking a function will work like so:
Private Function MyStringAlittleShorter(ByVal MyInputString As String, Byval Divider as integer) As String
Return MyInputString.Substring(1, MyInputString.Length / Divider)
End Function
...because I am returning the same type as I declared my function to be (even though one of the Byvals is of a different type).
Now your Byval is an array of type Object, which means that it can contain elements of different types. If you are also trying to return an array, and your function is declared boolean, you would get a type mismatch error. I.e. declare the function to be an array of type object, or perform the logic inside the function, and return a boolean.
Maybe that is the case ?
As for your second question: if the array is of type Object, than you should be able to add new elements of any type. You might get Index out of bounds errors ofcourse.
Hope it helps,
Johan

You also need to learn to type. Post your code and someone will help - if they can understand your question.

hi all,
i have developed an application in vb.net and mssql 2000 and create some reports using crystal reports. it is working perfectly on my pc but create some problem on my client's pc.
i used an ODBC Connection Say CrRptOdbc while creating Crystal reports.
normaly i have to create an odbc connection on the Client's pc when i install my application.
in this particular case my client has MS SQLExpress 2005. when i created a SETUP i attached the database file in it. But when i install the same on the client's pc other than Crystal Reports rest is working perfectly.
when i try to fetch a report it show me a dialog box which demand user id and password when i always used Window's Authitications. i tried to create ODBC connection but could not find the file which i attached.
kinly help me how can i configure my crystal reports in this case.
Thanks.

Hi
You can use dataset For Crystal Report.it's easiast way to use the crystal report.
With the dataset connection string,User Id,Password is not needful.

WPF is the way to go to create controls like this. This means your whole app will use WPF.

VB.net and C# has the facility for creating the control.

Hiya,
That sort of thing probably would not be a control, you would have to write the code for that yourself, which would probably have to be written in C++/C# and it would need a lot of code! Or you could use WPF in there somewhere, but that requires a lot of overhead and can be slow on some computers, but WPF can be quite good.

I have created an aspx page which displays the list of books in a grid when we search according to a search condition. If i click for details of the book it is displayed in another page. if I need to return to the page where the list is displayed usin a hyperlink or link button what should I do?

You should start by asking in the ASP.NET forum.
You will end up passing the details on the URL so the page goes to where you want it to.

As you are doing a postback, the referrer will be the same page.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
sorry but postback url doesnot take me to the previous page but it takes me to the page where I have to make the search again.
|
|
|
|
|
If the URL of the page containing the search result doesn't represent that page uniquely (i.e. you just populate the result on postback), then your only option to return to that page is to use the history in the browser to go back, so that the post data is resent to recreate the page.

A quick and easy way to go back to the previous page is to use javascript,
onClick="history.back()"
But as Christian said, you should post on the correct forum in future.
|
|
|
|
|
yhanks for your suggestion. I will surely try this out. Tell me this "history.back()" is a predefined function or should we write the script?
