The manual that came with the UPS is what you need. if it doesn't say that it offers that sort of functionality, then you probably cannot do it

Any one know where I can find information, I could not Google any thing.
It's a font name.
|
|
|
|
|
I think it's more of a corrupted font name. It's impossible to say which one it really is.

Hi All,
I am using C# 2.0. I have a form with few controls such as Panel, TextBox, ListBox, GridView and etc. I am trying to resize all the controls in runtime when user resize the form by dragging form borders and I am doing this by setting Anchor property of all the controls to all sides (right,left,top,bottom) and the Dock property = None. Everything works fine ,but if I set form property AutoScroll = true then controls doesn’t resize. Any idea why? Please help.
Thanks in advance!

BEcause it scrolls instead of sizing ?

I have an application that needs to record data in a database and the particular date when that data was written to the database. More, I need customers to be able to retrieve data from the database by date or date range. To that end, the MS Access database I'm using has a field called TestDate of type Date/Time, and I set up two date/time pickers to allow customers to select a date or date range from which to get data.
All this works well and good until I change my regional/language options so the date format changes, say from mm/dd/yyyy to dd/mm/yyyy. Then, although the MS Access database updates the TestDate data automatically to reflect the change in date/time format and my date/time pickers in the C# appilcation reflect the altered format, the result of executing SQL statements based on the date/time pickers does not return the correct data from the database.
Rather, selecting all data from December 10, 2007 retrieves data from October 12, 2007. By contrast, if I select, say November 29, 2007, the correct data is returned. Something, then, is getting confused about ambiguous dates.
Any suggestions would be appreciated.

You are storing using DateTime fields from the textboxes aren't you, rather than using a string? More importantly, you are using a parameter to put the field into the database aren't you?
If you want to force a UTC date, then you use the U format qualifier with the DateTime. For example
DateTime dt = DateTime.Now;
Console.WriteLine(dt.ToString("U"));

Yes, I am using a parameterized query to insert new records into the database and storing the data using the DateTime data type rather than a string.
Still, somewhere between picking the datetime for the SELECT statement and retrieving the data from the database, the date time format gets lost in translation. If I select a non-ambiguous date such as 13/09/2007 (September 13, 2007), execution of the SQL command returns the correct data, but selecting an ambiguous date, such as 3/12/2007 (intending December 3, 2007) returns erroneous data. The report shows 12/3/2007 (March 12, 2007), but the value of the date prior to the execution of the SQL statement is 3/12/2007 (December 3, 2007).

Hi, I'm learning C# by lurking the forums, but have much experience in Access. This solution works in Access, and I think it will work in C# but haven't tested yet.
In an Access query you have to enclose the date in # to force american date format.
This is how I do this (In Access)
Function ScriptaUDF(Datum As Date)
ScriptaUDF = "#" & Trim(Str(Month(Datum))) & "/" & Trim(Str(Day(Datum))) & "/" & Trim(Str(Year(Datum))) & "#"
End Function
So whenever I need a date in a query I use:
where (((Table.datefield) = " & ScriptaUDF(Me!Datefield) & "))
I hope this helps

That's interesting. The problem I've been having occurs, seemingly, during the execution of the SQL statement. I enclose my SQL SELECT statements with a # sign currently, so
"SELECT * FROM Table WHERE Date BETWEEN #" startdate #" AND #" endate"
If the # character forces an American date format, that would explain much, I think.
|
|
|
|
|
How would I specify a date in a SQL expression without forcing the american date format? Is there something I can use to insert a date in the SQL query without using the # sign? Or, if I use the # sign, can I simply force the format that is needed?

I found a solution. Basically, the Jet Engine seems to have problems with translation. To get the correct data, I have to do this:
SELECT * FROM TABLE WHERE Date BETWEEN Format(#" + startDate + "#,'mm/dd/yyyy')AND Format(#" + endDate + "#,'mm/dd/yyyy')
By setting the format in the SQL statement to United States format, the data seems to come back to me correctly.

If I have a text file containing the first line like this:
John 1976 200,000 United States
How do I import it to the database specifying that the first column should be John, second is 1976, third is 200,000, and last column is United States?
What are the commands/syntax being used to achieve this? Thanks.

Your text file format is a disaster. So long as country is the only field that can have a space in it, you may be OK. You use the string.Split method to turn this into a string array. If there's a fifth or sixth element, you append those to the fourth ( that's the country ). Then you have values to stuff into the database.

Thanks. How do we use bcp or bulk insert to import the data in text file into the database? I haven't done anything with databases or ADO.Net so I might need some step by step procedure to do this.

In that case, I'd recommend going through an article on the topic, on this site or elsewhere. It's just going to cover things in far more depth and clarity than I can hope to do in a forum reply.

I answered a question a few posts ago, where a user thought that assigning reference types was creating aliases for the names of those types. After thinking about it, I began to wonder if there IS a way to do this, so that you have two instances referencing the same pointer to the object. For example, is there a way to do the following in C# (I doubt it, because it was often the cause of many problems in C++, but just thought I would ask)?
object A = new object();
object B = ref A;
B = new object();
Hope this question makes sense. Thanks,
Sounds like somebody's got a case of the Mondays

Hi Jeff,
I have never seen such thing, so AFAIK it is impossible.
Also, IMO the C# language designers would consider it unnecessary and unsafe.
And if you look at pointers, they can only point to value types.
So I think you will have to refactor the code and substitute every B by A.
[added]
the feature you're asking about is similar to the union in C/C++;
it is not supported in C#, although there is a way to mimic it inside structs,
by giving explicit FieldOffset values
I use unions (in C that is) only to byte-convert from one type to another, not to get two names for
the same thing; sometimes I miss it in C#. Not sure how the C# compiler would cope with the latter.

Yeah, I remembered doing it in C++ before, but couldn't remember what the keyword was. I don't really have a need (nor see a need) to do this, since, as you said, I could just substitute the variable A for all occurances of B and still have identical code. This is a feature that I think should NOT have been implemented in C#, so I am glad to see that it isn't. Thanks Luc,

After googling for a while, I determined that the code I was refering to in C++ would have looked something like this (I think)...
int i = 0;
int j = &i;
j = 5; I think that the previous code forces i and j to always be equivalent, but again, it has been a while since I programmed in C++, so I can't be certain. Thanks,

Skippums wrote: int j = &i;
that would not compile, it should be int* j = &i; so there is only a single
int, and a pointer that now points to the same int. So changing it either with i=...
or with *j=... results in changing the single int, whatever way you access it,
it is still a single variable.

I was wondering if there is a simple number format code for if you only want to see the decimal portion of the number if there are any significant digits to the right of the decimal - otherwise show the number as an integer.
ex. 3.5 -> 3.5 and 3.0 -> 3 (instead of 3.0)
Thanks

Use something like:
num.ToString("0.#")
This will display the string representation of the number including the first significant digit to the right of the decimal point if required.
