getting " Object type cannot be converted to target type." with dataAdapter using storedProc

i'm getting an error when trying set my dataAdapter's selectCommand. the
sqlStatement is a storedProc which takes parameters, so it's constructed as:

sqlSelectComman d1.CommandText = "[uspProjectListU ser]";

sqlSelectComman d1.CommandType = System.Data.Com mandType.Stored Procedure;

sqlSelectComman d1.Connection = sqlConnection1;

sqlSelectComman d1.Parameters.A dd(new
System.Data.Sql Client.SqlParam eter("@RETURN_V ALUE",
System.Data.Sql DbType.Int, 4, System.Data.Par ameterDirection .ReturnValue,
false, ((System.Byte)( 0)), ((System.Byte)( 0)), "",
System.Data.Dat aRowVersion.Cur rent, null));

sqlSelectComman d1.Parameters.A dd("@iCompanyID ", SqlDbType.Int). Value = 1;

sqlSelectComman d1.Parameters.A dd("@iUserID", SqlDbType.Int). Value = 4;

when i pass this to my dataAdapter as:

oDataAdapter.Se lectCommand = sqlSelectComman d1;

i get an error:

" Object type cannot be converted to target type."

i've tried commenting out the parameters, and then have no problems setting
the dataAdapter's selectCommand.

how can i fix this?

tks

Please forgive the simplicy of this question. I have the following code which attempts to determine the color of some text and set other text to match that color. It works fine in Firefox, but does nothing in IE. I'd be greatful for any assistance. Also, if I will have problems the code on Opera or Safari, I'd appreciate any pointers--I don't have a Mac to test Safari. THanks very much, Michael

I have 2 questions: 1. strlen returns an unsigned (size_t) quantity. Why is an unsigned value more approprate than a signed value? Why is unsighned value less appropriate? 2.

I know that I have posted this question before, but it is still unresolved and I don't know where to turn to next. I have code that is creating a user (works fine), then sets the account flags (works fine) and then sets the password (fails). Here is the pertinent information: Ex.InnerException.Message: Logon failure: unknown user name or bad password. Ex.Message: Exception has been thrown by the target of an invocation.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
